Tension-Type Headache: Causes and Treatment
For acute tension-type headache, use ibuprofen 400 mg or acetaminophen 1000 mg, and for prevention of chronic tension-type headache, use amitriptyline. 1
Causes and Pathophysiology
Tension-type headache (TTH) is the most prevalent primary headache disorder worldwide 2, 3. The underlying mechanisms involve:
- Peripheral mechanisms: Increased muscle tenderness and myofascial trigger points in the cranio-cervical-mandibular region 2
- Central sensitization: Plays a critical role in transformation from episodic to chronic TTH, with altered pain processing in cortical and subcortical brain regions 2, 3
- Genetic predisposition: Contributes to susceptibility 2
- Psychological factors: Anxiety and depression are significant comorbidities that may contribute to central sensitization underlying frequent TTH 2, 4
The headache is characterized by bilateral location, pressing or tightening quality, mild to moderate intensity, and no aggravation by routine physical activity 3.
Treatment Approach
Acute Treatment (Episodic TTH)
The 2023 VA/DoD guidelines provide a weak recommendation for ibuprofen 400 mg or acetaminophen 1000 mg for short-term treatment 1. These simple analgesics are first-line medications with evidence-based effectiveness 3, 5.
Other NSAIDs like aspirin and naproxen are also reasonable options 1.
Preventive Treatment (Chronic TTH)
The guidelines suggest amitriptyline for prevention of chronic tension-type headache 1. This tricyclic antidepressant is considered the gold standard for prophylaxis 3, 6, 5.
Other options mentioned in the literature include:
- Venlafaxine and mirtazapine 3
- Nonhabituating anxiolytic or antidepressant medications for patients with underlying depression or persistent anxiety 6
Non-Pharmacological Interventions
Physical therapy or aerobic exercise can be used in management of TTH 1. The evidence supports:
- Physical therapy: Approaches targeting the cranio-cervical-mandibular region show significant effects in decreasing pain intensity and headache frequency in the short and medium term 7
- Cognitive behavioral therapy: Valuable component of comprehensive management 2
- Biofeedback: Effective in multiple studies 4, 6
- Neuromodulation techniques: Emerging option 2
- Mindfulness and lifestyle management: Important adjuncts 2
Important Caveats
- Botulinum toxin is NOT recommended: The guidelines suggest against botulinum/neurotoxin injection for prevention of chronic TTH 1, distinguishing it from chronic migraine where it has a role
- Medication overuse: Excessive analgesic use may limit treatment effectiveness and should be monitored 4
- Comorbid psychiatric disorders: Must be addressed, as anxiety or depression contribute to central sensitization 4
- Combined approach: The combination of behavioral and preventive drug therapies may improve outcomes, particularly for chronic TTH 4
Treatment Algorithm
- For episodic TTH: Start with ibuprofen 400 mg or acetaminophen 1000 mg as needed 1
- If headaches become frequent or chronic: Consider amitriptyline for prevention 1
- Add non-pharmacological interventions: Physical therapy targeting the cranio-cervical region and/or cognitive behavioral therapy 1, 2, 7
- Screen and treat: Evaluate for comorbid anxiety/depression and address these conditions 2, 4
The integrated multidisciplinary approach combining pharmacological and non-pharmacological interventions is critical for optimal patient outcomes 2.
