Tremor disorders are a group of neurological conditions characterized by involuntary, rhythmic oscillatory movements of a body part, most commonly affecting the hands. Tremors may occur at rest, during posture maintenance, or with voluntary movement. They can arise as primary neurological disorders or as manifestations of underlying systemic or neurodegenerative disease.

Essential tremor is the most common tremor disorder and typically presents as a bilateral action tremor affecting the hands and forearms. Other tremor types include Parkinsonian tremor, cerebellar tremor, dystonic tremor, and tremor secondary to metabolic or drug-related causes. Accurate classification is critical, as treatment varies significantly between tremor subtypes.

Neurological evaluation involves detailed history, examination, and assessment of tremor characteristics. Neuroimaging and laboratory testing may be required to exclude secondary causes. Differentiating tremor disorders from other movement disorders is essential to avoid misdiagnosis.

Management of tremor disorders is individualized and depends on symptom severity and functional impact. Medical therapy aims to reduce tremor amplitude and improve daily functioning. Not all tremors require treatment, particularly when mild and non-disabling.

Tremor disorders can significantly affect quality of life, particularly when they interfere with fine motor tasks. Neurologists provide long-term monitoring and adjust therapy as symptoms evolve.

In the UAE, tremor disorders are managed within specialized neurology services, emphasizing accurate diagnosis, evidence-based treatment, and functional preservation.
