Tremors
Tremors are involuntary, rhythmic muscle contractions that result in shaking movements in one or more parts of the body. They can occur at rest or during movement and can affect various parts of the body, including the hands, arms, head, face, voice, trunk, and legs. Here’s an overview of the causes, types, diagnosis, and treatment options for tremors:
Causes of Tremors:
- Neurological Disorders
- Medical Conditions
- Medications
- Substance Abuse
- Genetic Factors
Types of Tremors:
Essential Tremor:
- The most common type of tremor, usually affecting the hands, head, and voice.
- Often runs in families (genetic).
Parkinsonian Tremor:
- Associated with Parkinson’s disease.
- Typically occurs at rest and improves with movement.
Dystonic Tremor:
- Occurs in people with dystonia (a movement disorder characterized by involuntary muscle contractions).
- Can affect any part of the body.
Cerebellar Tremor:
- Results from damage to the cerebellum (part of the brain that controls movement).
- Occurs at the end of a purposeful movement, such as touching your nose.
Psychogenic Tremor:
- Caused by psychological factors such as stress or psychiatric disorders.
- Often associated with other psychiatric symptoms.
Physiologic Tremor:
- A normal tremor that everyone has but is usually not noticeable.
- Can become more pronounced due to factors like anxiety, fatigue, caffeine, or certain medications.
