What are Tension-Type Headaches?
Tension-Type Headache (TTH) is the most common primary headache disorder characterized by a bilateral, mild to moderate, pressing or tightening pain, often described as a "band-like" sensation around the head. Unlike migraine, TTH typically lacks significant nausea, vomiting, or pronounced sensitivity to light and sound. It can be episodic or chronic, and although less disabling than migraine, it can significantly affect quality of life when frequent or persistent.

Epidemiology of Tension-Type Headaches (TTH)
Tension-Type Headaches (TTH) affect a large proportion of the population worldwide, with a lifetime prevalence estimated at 30–78%. It is slightly more common in females than in males and can occur at any age, but the onset is most common in adolescence or early adulthood. Episodic TTH is very common, while chronic TTH, defined as headaches occurring on 15 or more days per month for more than 3 months, affects approximately 2–3% of the general population.

Causes of Tension-Type Headaches
The exact causes of tension-type headaches are not fully understood, but it is generally believed that a combination of biological, psychological, and environmental factors contributes to their development. One of the primary contributors is muscle tension and myofascial trigger points in the head, neck, and shoulder regions. Prolonged contraction or tightness of these muscles can stimulate pain receptors, sending pain signals to the brain and resulting in the characteristic pressing or tightening sensation experienced during TTH. This muscular tension may be related to poor posture, repetitive strain, or sustained physical activity that stresses these muscle groups.
In addition to peripheral muscle factors, central nervous system sensitization plays an important role in chronic tension-type headache. Prolonged nociceptive input from muscles and other tissues can cause the brain and spinal cord to become more sensitive to pain signals, lowering the threshold for pain perception. This central sensitization explains why some patients experience frequent or chronic headaches even in the absence of ongoing muscle tension.
Psychological factors such as stress, anxiety, and depression are strongly associated with tension-type headaches. Emotional stress can increase muscle tension and alter pain processing pathways in the brain, exacerbating headache frequency and severity. Individuals experiencing high levels of psychosocial stress are more likely to develop TTH and to have more disabling headaches.
Environmental and lifestyle factors also contribute to the onset and worsening of tension-type headaches. Poor sleep quality, fatigue, eye strain (from prolonged screen use or poor lighting), and irregular meal patterns can all precipitate headaches. Additionally, some individuals are sensitive to certain triggers such as noise, glare, or changes in weather, which may aggravate TTH symptoms.
Finally, while tension-type headache is primarily a primary headache disorder, secondary causes such as cervical spine disorders, temporomandibular joint dysfunction, and dental problems can mimic or worsen TTH symptoms. Therefore, it is important to consider these underlying conditions when evaluating and managing patients with persistent headaches.
Triggers of Tension-Type Headaches
Tension-type headaches are often triggered by a variety of factors that increase muscle tension, stress, or alter normal neurological processing. One of the most common triggers is psychological stress. Emotional stress from work, family, or personal issues can lead to increased muscle tension in the head, neck, and shoulders, which may precipitate or worsen headaches. Stress also affects neurotransmitter levels and pain modulation in the brain, making individuals more susceptible to headache attacks.
Poor posture is another frequent trigger. Maintaining an awkward or strained posture for prolonged periods—such as hunching over a computer, looking down at a phone, or holding the neck in an unnatural position—can cause muscle fatigue and tightness, leading to headache onset. This is particularly common in office workers and students who spend extended hours seated at desks.
Sleep disturbances, including insufficient sleep, irregular sleep patterns, or poor sleep quality, are well-recognized triggers for tension-type headaches. Sleep deprivation increases pain sensitivity and can contribute to muscle tension, both of which promote headache development. Conversely, oversleeping or changes in normal sleep routines may also provoke headaches in some individuals.
Environmental factors such as eye strain from excessive screen time, bright lights, or glare can trigger headaches by causing both muscular tension (especially in the forehead and around the eyes) and neurological stress. Similarly, exposure to loud noises, strong smells, or uncomfortable temperatures can act as external triggers in susceptible individuals.
Other lifestyle-related triggers include hunger or dehydration, where low blood sugar or inadequate fluid intake may lower the pain threshold and provoke headaches. Additionally, caffeine withdrawal is a known precipitant for headaches, including tension-type headaches, especially in habitual coffee or tea drinkers who abruptly reduce their intake.
Finally, some people experience TTH triggered or worsened by physical exertion or fatigue. Overuse of the neck and shoulder muscles during exercise or heavy physical labor can increase muscle tightness and pain, contributing to headache development.
Subtypes of Tension-Type Headache (ICHD-3 Classification)
Tension-type headache (TTH) is the most prevalent primary headache disorder and is classified into distinct subtypes based on attack frequency and duration. The International Classification of Headache Disorders, 3rd edition (ICHD-3) provides clear diagnostic criteria for these subtypes, which are essential for accurate diagnosis, treatment, and prognosis.
The main subtypes include:
✔ Infrequent Episodic TTH,
✔ Frequent Episodic TTH, and
✔ Chronic TTH.
Infrequent Episodic Tension-Type Headache
Infrequent episodic TTH is characterized by headache attacks occurring fewer than 12 days per year. The headache episodes last from 30 minutes up to 7 days, though they typically resolve sooner. The pain is usually bilateral, described as pressing or tightening (non-pulsating) in quality, and of mild to moderate intensity. It is not aggravated by routine physical activity such as walking or climbing stairs. Unlike migraine, nausea and vomiting are absent. Photophobia or phonophobia may be present, but not both simultaneously, and if present, symptoms are mild. These headaches cause little or no disability and generally respond well to simple analgesics such as paracetamol or NSAIDs.
Frequent Episodic Tension-Type Headache
Frequent episodic TTH presents with headaches occurring between 12 and 179 days per year, reflecting an increase in frequency compared to the infrequent subtype. The clinical characteristics of the headache attacks are similar to infrequent episodic TTH in terms of pain quality, location, and associated symptoms. The intensity remains mild to moderate, and routine physical activities do not exacerbate the pain. Patients with frequent episodic TTH may begin to experience increased muscle tenderness in the pericranial muscles, particularly in the scalp, neck, and shoulders. This subtype may interfere more noticeably with daily activities but still usually does not cause significant disability.
Chronic Tension-Type Headache
Chronic TTH is defined by headache occurring on 15 or more days per month for at least 3 consecutive months (i.e., 180 or more days per year). The pain typically has the same pressing or tightening quality but can persist for longer durations, ranging from hours to days or even be continuous. The intensity is usually mild to moderate, but because of the high frequency, the cumulative disability can be substantial. Mild nausea and either photophobia or phonophobia may occasionally be present, but never both simultaneously, and vomiting is absent. Chronic TTH is often associated with increased pericranial muscle tenderness and can be complicated by psychological comorbidities such as anxiety or depression. This subtype tends to be more resistant to treatment and may require preventive therapy combined with behavioral and physical interventions.
Probable Tension-Type Headache
The ICHD-3 also recognizes Probable TTH, which applies when a headache fulfills most but not all of the criteria for one of the defined TTH subtypes. This category allows for flexibility in diagnosis when presentations are atypical or incomplete but still consistent with TTH. Probable TTH is important in clinical practice because many patients may initially present with symptoms that do not perfectly fit strict diagnostic boundaries.
Additional Notes on Related Conditions
While not classified as TTH subtypes, some important related conditions include Medication-Overuse Headache (MOH) and Tension-Type Headache with Pericranial Tenderness. MOH is a secondary headache disorder caused by frequent use of analgesics or headache medications, commonly complicating chronic TTH and worsening its course. Pericranial muscle tenderness is a key clinical finding often seen in TTH, especially chronic forms, and supports the involvement of muscle factors in the pathophysiology.
The ICHD-3 classification of tension-type headaches into infrequent episodic, frequent episodic, and chronic subtypes provides a practical framework for diagnosis and management. The subtypes differ mainly by attack frequency and duration but share common features in pain quality and associated symptoms.(alert-passed)
Clinical Features of Tension-Type Headaches
The hallmark feature of tension-type headache is a bilateral, pressing or tightening pain that is often described as a band-like sensation around the head. The pain is typically mild to moderate in intensity and is usually steady rather than pulsating. Unlike migraine, the pain does not worsen with routine physical activities such as walking or climbing stairs. Patients frequently describe the sensation as a dull, aching pressure or tightness rather than sharp or throbbing pain.
Location of Pain
TTH pain commonly involves the frontal, temporal, and occipital regions of the head, often symmetrically on both sides. Some patients also report discomfort in the neck and shoulder muscles, which may contribute to or exacerbate the headache. The pain may feel like a tight band encircling the forehead or the back of the head and neck.
Duration and Frequency
The duration of TTH episodes varies widely depending on the subtype. In episodic TTH, headaches can last from 30 minutes to several hours, occasionally extending up to 7 days. In chronic TTH, headaches occur on 15 or more days per month and can persist continuously or intermittently throughout the day. Frequency also varies, ranging from a few attacks per year in infrequent episodic TTH to daily or near-daily headaches in chronic forms.
Associated Symptoms
Unlike migraines, TTH is generally not associated with nausea or vomiting. However, some patients may experience mild photophobia (sensitivity to light) or phonophobia (sensitivity to sound), but rarely both simultaneously. These symptoms are usually less intense than those seen in migraine and are not considered disabling. There is also usually no aura or neurological symptoms preceding the headache.
Physical Examination Findings
During clinical examination, patients with TTH may show tenderness or increased tension in the pericranial muscles, including the scalp, neck, and shoulders. This tenderness is often bilateral and can be reproduced by palpation. Neurological examination is typically normal, which helps differentiate TTH from secondary headaches caused by structural brain lesions or other pathology.
Impact on Daily Life
While TTH is usually less disabling than migraine, frequent or chronic tension-type headaches can significantly affect quality of life. Patients may report difficulty concentrating, fatigue, or irritability during headache episodes. Chronic TTH, in particular, can contribute to mood disturbances such as anxiety and depression, potentially creating a cycle of pain and psychological distress.
Tension-type headaches are characterized by bilateral, pressing, mild to moderate head pain, often associated with pericranial muscle tenderness. They lack the severe nausea, vomiting, and aura of migraines and typically do not worsen with physical activity.(alert-passed)
Complications of Tension-Type Headaches
Tension-type headaches are a common type of headache that can cause discomfort and pain. While they are typically not associated with serious complications, they can still have an impact on a person's quality of life.
A. Chronicity and Increased Frequency
One of the main complications of tension-type headaches is the progression from episodic to chronic tension-type headache. Frequent episodic TTH, if untreated or poorly managed, can evolve into chronic TTH, characterized by headaches occurring 15 or more days per month for over three months. Chronic TTH often results in persistent daily or near-daily headaches, which are more difficult to treat and can significantly impair a person’s quality of life. This transition may be driven by central sensitization processes in the nervous system, making headaches more frequent and intense over time.
B. Medication Overuse Headache (MOH)
A significant complication, especially in chronic tension-type headache sufferers, is the development of medication-overuse headache. MOH occurs when patients frequently use pain relief medications—such as acetaminophen, NSAIDs, or combination analgesics—to manage their headaches. Instead of providing relief, overuse paradoxically causes an increase in headache frequency and severity, creating a vicious cycle of pain and medication dependence. MOH complicates diagnosis and management and often requires withdrawal of the offending medications and careful preventive therapy.
C. Psychological and Psychiatric Comorbidities
Chronic tension-type headache is frequently associated with psychological complications such as anxiety, depression, and stress-related disorders. The persistent pain and disability caused by frequent headaches can lead to emotional distress, reduced coping ability, social withdrawal, and decreased productivity. These psychiatric comorbidities may, in turn, exacerbate headache frequency and intensity, creating a challenging cycle that requires integrated medical and psychological treatment approaches.
D. Reduced Quality of Life and Functional Impairment
Although tension-type headaches are generally less disabling than migraines, their frequent or chronic occurrence can cause substantial impairment in daily functioning. Patients may experience difficulty concentrating, impaired work performance, fatigue, and reduced participation in social and recreational activities. This can lead to diminished overall well-being and affect relationships and mental health.
E. Musculoskeletal Complications
Due to the strong association of TTH with pericranial muscle tension, patients may develop muscle tightness, spasms, or trigger points in the neck, shoulders, and scalp muscles. Chronic muscle tension can contribute to persistent pain and discomfort beyond headache episodes, leading to posture-related issues and musculoskeletal strain. These physical complications may perpetuate headache symptoms and complicate treatment.
While tension-type headaches are often perceived as mild and benign, their complications—especially chronicity, medication overuse, psychological distress, and reduced quality of life—can have significant impacts on patients. Early diagnosis, effective treatment, and preventive strategies are essential to minimize these complications and improve patient outcomes.(alert-passed)
Diagnosis of Tension-Type Headaches
The diagnosis of Tension-type headaches is usually made based on clinical criteria, including the characteristics of the headache and the presence or absence of other symptoms.
A. Clinical History
The diagnosis of tension-type headache is primarily clinical and begins with a thorough patient history. Patients typically describe a bilateral, pressing or tightening headache of mild to moderate intensity. The pain usually lasts from 30 minutes to several hours but can persist for days, especially in chronic cases. It is important to ask about headache frequency—episodic TTH occurs fewer than 15 days per month, whereas chronic TTH occurs on 15 or more days per month for at least three months. Associated symptoms such as nausea and vomiting are usually absent, and photophobia or phonophobia, if present, are mild and not simultaneous. The absence of aggravation by routine physical activity helps differentiate TTH from migraine.
B. Physical and Neurological Examination
Physical examination often reveals pericranial muscle tenderness—patients may have increased sensitivity or tightness in the muscles of the scalp, neck, and shoulders. This muscle tenderness supports the diagnosis of TTH and may be more pronounced in chronic cases. Neurological examination should be completely normal in TTH patients; the presence of any focal neurological deficits warrants further investigation for secondary causes of headache.
C. Diagnostic Criteria (ICHD-3)
The International Classification of Headache Disorders, 3rd edition (ICHD-3), provides specific criteria to diagnose TTH:
🔹 At least 10 episodes of headache fulfilling the following:
🔹 Headache lasting from 30 minutes to 7 days
🔹 At least two of the following characteristics: bilateral location, pressing/tightening quality, mild or moderate intensity, not aggravated by routine physical activity
🔹 Both of the following: no nausea or vomiting, and no more than one of photophobia or phonophobia
🔹 The headaches are not better accounted for by another diagnosis.
Meeting these criteria is essential to differentiate TTH from other primary headaches like migraine or secondary headaches.
D. Exclusion of Secondary Headaches
Because tension-type headaches are a diagnosis of exclusion, it is important to rule out secondary causes of headache that may mimic TTH. Warning signs (“red flags”) include sudden onset of severe headache, neurological symptoms, changes in headache pattern, systemic symptoms (fever, weight loss), and headaches triggered by physical exertion or Valsalva maneuver. In such cases, neuroimaging and further investigations may be necessary.
E. Use of Headache Diaries and Questionnaires
Encouraging patients to keep a headache diary can help track the frequency, duration, severity, and possible triggers of headaches. This information aids in differentiating episodic from chronic TTH and identifying medication overuse. Validated questionnaires can also assess the impact of headaches on quality of life and screen for comorbid conditions like anxiety and depression.
Diagnosis of tension-type headache relies on a detailed history and physical examination guided by established criteria, with careful exclusion of secondary headaches.(alert-passed)
Management of Tension-Type Headaches
The management of tension-type headaches aims to relieve acute pain, reduce headache frequency, and improve overall quality of life. Treatment strategies include pharmacological and non-pharmacological approaches tailored to the subtype of TTH (episodic or chronic), the frequency and severity of headaches, and individual patient factors. Preventing progression to chronic headache and avoiding medication overuse are also key goals.
A. Acute (Abortive) Treatment
For episodic tension-type headaches, acute treatment focuses on relieving pain during attacks. Simple analgesics such as acetaminophen (paracetamol) and nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are first-line options. These medications are effective for mild to moderate pain and generally well-tolerated when used appropriately. Combination analgesics containing caffeine may also provide relief, but should be used cautiously to avoid dependence. It is important to limit the frequency of analgesic use to prevent medication-overuse headache.
It is important to note that overuse of analgesics and NSAIDs can lead to medication overuse headache (MOH). Patients should be cautioned against using these medications more than two to three times a week to avoid MOH.
B. Preventive Treatment
Preventive therapy is considered for patients with frequent episodic or chronic tension-type headaches who experience significant disability or when acute treatments are insufficient or overused. The tricyclic antidepressant amitriptyline is the most widely studied and effective preventive medication. Low doses (e.g., 10–75 mg at bedtime) can reduce headache frequency and intensity, partly by modulating central pain pathways. Other antidepressants, such as mirtazapine or venlafaxine, may be considered when amitriptyline is not tolerated. In some cases, muscle relaxants or anticonvulsants might be used, though evidence is less robust.
C. Non-Pharmacological Therapies
Non-drug treatments play a crucial role in managing TTH and may be used alone or in combination with medications. Stress management techniques—including relaxation training, biofeedback, cognitive-behavioral therapy (CBT), and mindfulness meditation—can help reduce headache frequency by addressing psychological triggers and muscle tension. Physical therapies such as massage, physiotherapy, and exercises targeting the neck, shoulders, and upper back improve muscle flexibility and reduce pericranial tenderness. Ergonomic advice to improve posture and reduce muscle strain during daily activities is also beneficial.
D. Lifestyle Modifications
Educating patients about lifestyle factors that contribute to TTH is vital for long-term management. Recommendations include maintaining regular sleep patterns, avoiding prolonged screen time or poor posture, staying hydrated, and managing stress effectively. Regular physical activity and balanced nutrition also support overall well-being and may reduce headache frequency.
E. Management of Medication-Overuse Headache
For patients who develop medication-overuse headache (MOH) complicating chronic TTH, the key management step is the withdrawal of overused medications. This process may require supervised tapering or abrupt cessation, depending on the medication type and patient tolerance. Preventive therapies and non-pharmacological treatments are essential to support withdrawal and prevent relapse. Patient education about the risks of frequent analgesic use is critical.
F. Follow-Up and Monitoring
Regular follow-up allows monitoring of treatment efficacy, medication side effects, and adherence to lifestyle changes. Use of headache diaries helps track headache patterns and treatment responses. Adjustment of therapies based on clinical response and patient preference ensures optimal long-term control. Psychological support may be required in cases with comorbid anxiety or depression.
Effective management of tension-type headaches involves a multimodal approach combining acute pain relief, preventive medications, non-pharmacological therapies, lifestyle modifications, and education to avoid medication overuse. Early intervention and individualized treatment plans improve patient outcomes and reduce the risk of chronic headache.(alert-passed)
Prevention of Tension-Type Headaches
Prevention of tension-type headaches focuses on reducing the frequency, severity, and impact of headache episodes through lifestyle modifications, management of risk factors, and, when necessary, pharmacological interventions. Effective prevention not only improves quality of life but also reduces the risk of headache chronification and medication overuse.
A. Lifestyle Modifications
A cornerstone of TTH prevention is adopting healthy lifestyle habits. Maintaining a regular sleep schedule is crucial since both insufficient and excessive sleep can trigger headaches. Adequate hydration and balanced nutrition also play important roles, as dehydration and skipping meals may precipitate headache attacks. Reducing prolonged screen time and ensuring proper ergonomics during work or study—such as correct posture and frequent breaks—helps prevent muscle strain that can contribute to headaches. Regular physical exercise promotes general well-being and may reduce muscle tension and stress, both known headache triggers.
B. Stress Management
Stress is a common precipitant of tension-type headaches, so developing effective stress management strategies is vital. Techniques such as relaxation training, deep breathing exercises, meditation, yoga, and biofeedback can help patients control physiological responses to stress and reduce muscle tension. Cognitive-behavioral therapy (CBT) may be beneficial for patients with chronic headaches or those experiencing anxiety and depression alongside TTH. Encouraging patients to identify and address psychosocial stressors can also diminish headache frequency.
C. Ergonomic and Musculoskeletal Care
Preventing TTH often involves minimizing strain on the neck, shoulder, and scalp muscles. Ergonomic adjustments in the workplace or home—like using supportive chairs, adjusting computer screen height, and positioning keyboards correctly—help maintain good posture and prevent musculoskeletal tension. Regular stretching exercises and physiotherapy targeting pericranial muscles can reduce muscle tightness. Massage therapy may also aid in relieving muscle tension and improving circulation.
D. Pharmacological Prevention
For patients with frequent or chronic tension-type headaches that significantly impair daily functioning, pharmacological prophylaxis may be indicated. The tricyclic antidepressant amitriptyline is the most commonly used preventive medication, effective at low doses for reducing headache frequency and severity. Other antidepressants such as mirtazapine or venlafaxine may be alternatives if amitriptyline is not tolerated. Preventive medications should be started at low doses and titrated slowly under medical supervision. It is important to counsel patients regarding potential side effects and the need for adherence to the treatment plan.
E. Avoidance of Medication Overuse
Preventing medication-overuse headache (MOH) is an important aspect of TTH prevention. Patients should be educated to avoid frequent or excessive use of over-the-counter analgesics or combination medications. Limiting acute pain medication use to fewer than 10 days per month reduces the risk of MOH, which can worsen headache frequency and complicate management.
F. Regular Monitoring and Follow-Up
Ongoing follow-up allows healthcare providers to assess the effectiveness of preventive strategies and adjust treatments as needed. Encouraging patients to maintain headache diaries helps monitor triggers, medication use, and response to prevention efforts. Psychological support may be integrated into prevention plans for those with comorbid mood disorders or significant stress.
Prevention of tension-type headaches involves a comprehensive approach combining lifestyle modifications, stress management, ergonomic care, cautious use of pharmacological agents, and patient education. Early and sustained preventive efforts improve long-term outcomes and reduce the burden of this common headache disorder.(alert-passed)
Prognosis of Tension-Type Headaches
Tension-type headaches are among the most common primary headache disorders and generally have a favorable prognosis, especially in their episodic forms. Many individuals experience infrequent, mild headaches that do not significantly impair daily functioning or quality of life. However, the clinical course can vary widely among patients, with some progressing to frequent or chronic forms that may cause greater disability and require long-term management.
Episodic Tension-Type Headache Prognosis
Infrequent episodic TTH typically has an excellent prognosis. Most patients experience occasional headaches that respond well to simple analgesics and lifestyle modifications, with little impact on daily activities. These headaches often do not progress in frequency or severity, and many patients experience spontaneous remission over time. Frequent episodic TTH, while more persistent, can often be controlled with appropriate acute and preventive therapies, resulting in good functional outcomes.
Chronic Tension-Type Headache Prognosis
Chronic TTH has a more variable and often less favorable prognosis. Patients with chronic TTH experience headaches on 15 or more days per month for at least three months, sometimes daily or continuous in nature. Chronic headaches can lead to significant reductions in quality of life, including impaired work productivity, social isolation, and psychological distress such as anxiety and depression. The condition is frequently associated with medication-overuse headache (MOH), which can complicate treatment and prolong recovery. Although chronic TTH is more difficult to treat, many patients can achieve meaningful improvement through multidisciplinary management, including pharmacological prophylaxis, behavioral therapy, and lifestyle changes.
Risk Factors Affecting Prognosis
Several factors influence the prognosis of tension-type headaches. High headache frequency at onset, presence of chronic pain conditions, comorbid psychiatric disorders (especially depression and anxiety), and medication overuse are associated with poorer outcomes. Conversely, early diagnosis, patient education, adherence to treatment, and effective stress management improve prognosis. Patients who engage in regular physical activity and maintain healthy lifestyle habits tend to have better long-term control of headaches.
Long-Term Outlook and Complications
While many patients with episodic TTH have a benign and self-limiting course, there is a risk that recurrent headaches may increase in frequency and evolve into chronic tension-type headache over time. Chronic TTH can persist for years and significantly impact overall well-being if untreated. However, with appropriate intervention, many patients experience a reduction in headache frequency and severity. Importantly, preventing medication overuse is critical to avoid transformation to more refractory headache patterns.
Tension-type headaches generally carry a good prognosis, particularly in episodic forms. Chronic tension-type headaches are more challenging but can be managed effectively with comprehensive treatment. Early recognition, avoidance of medication overuse, management of psychological comorbidities, and lifestyle interventions are key factors that contribute to a favorable outcome.(alert-passed)
