Tremor is an involuntary, rhythmic muscle contraction leading to shaking movements in one or more parts of the body, often caused by neurological disorders or as a side effect of certain medications. It can be classified into various types, such as essential tremor, resting tremor, and intention tremor, each with distinct characteristics and underlying causes.

Tremor

Involuntary muscle contractions are automatic and unconscious movements that occur without intentional control, often as a reflexive response to stimuli or as part of normal physiological processes. These contractions can occur in various muscle types, including smooth and cardiac muscles, and are essential for functions such as digestion, heartbeat regulation, and maintaining posture.

Neurological disorders encompass a wide range of conditions affecting the nervous system, including the brain, spinal cord, and peripheral nerves. These disorders can result from genetic, environmental, or unknown causes and may lead to a variety of symptoms such as cognitive impairment, motor dysfunction, and sensory disturbances.

Types of tremor

Essential tremor is a neurological disorder characterized by involuntary and rhythmic shaking, most commonly affecting the hands, head, and voice. It is often hereditary and can worsen with stress, fatigue, or caffeine, but may improve with alcohol consumption.

Underlying causes are the hidden reasons why something happens, like the roots of a tree that you can't see but help it grow. Understanding these hidden reasons helps us solve problems better, just like finding out why a toy is broken helps us fix it.
