Dystonia is a movement disorder characterized by sustained or intermittent muscle contractions causing twisting, repetitive movements or abnormal postures. It can affect any body part — from a single muscle group (focal dystonia, e.g., cervical dystonia of the neck) to the whole body (generalized dystonia). Dystonia is often misdiagnosed as psychological or as a different movement disorder.
Types
Focal dystonia: single body region — cervical dystonia (neck, most common), blepharospasm (eyelids), writer's cramp, oromandibular dystonia. Segmental: adjacent regions. Multifocal/generalized: widespread. Task-specific: only during specific activities (writing, playing instrument).
Causes
Primary dystonia: genetic (DYT mutations), often begins in childhood/adolescence for generalized, adulthood for focal. Secondary dystonia: brain injury (stroke, trauma), medications (antipsychotics — tardive dystonia), metabolic disorders, neurodegenerative diseases.
Treatment
Botulinum toxin injections: first-line for focal dystonia — relaxes overactive muscles, effects last 3–4 months. Oral medications (anticholinergics, baclofen, clonazepam) for generalized. Physical therapy and sensory tricks help. Deep brain stimulation for severe generalized dystonia refractory to other treatments.
When to seek professional evaluation
Dystonia requires accurate diagnosis — because treatment (botulinum toxin, oral medication, DBS) depends on type, distribution and cause.

Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
Frequency may improve with systematic evaluation of types, contributors, and individualized planning, but outcomes vary.
Using pain medication on 10+ days per month can trigger daily headache. Reduction or cessation under medical supervision may help break this cycle.
