Tremors are involuntary and uncontrollable rhythmic movements that occur in specific areas of the body. These movements are a result of dysfunction in the part of the brain responsible for muscle control. While tremors are not always a cause for concern, they can be a symptom of serious disorders that require medical intervention. Treating tremors can be challenging, and in some cases, they may cease on their own over time if not associated with any underlying conditions. Here are five common types of tremors that individuals may experience throughout their lives.
Psychogenic Tremors
Psychogenic tremors are tremors that are caused by an underlying psychological condition. These tremors occur when psychological events or distress/dysfunction produce physical symptoms, or when illnesses stimulate bodily action for psychological reasons. Psychogenic tremors can affect any part of the body, and their intensity can vary from person to person. They typically develop suddenly and occur randomly, with periods of complete or partial remission. It has been observed that these tremors are usually less severe when the individual experiencing them is distracted or preoccupied.
Cerebellar Tremors: Causes and Symptoms
Cerebellar tremors are a type of tremor characterized by a slow trembling of the extremities. These tremors typically occur at the end of purposeful movements, such as pressing a button or poking something. The main cause of cerebellar tremors is damage or lesions to the cerebellum, which can result from various conditions including strokes, tumors, and other neurological disorders.
In addition to these causes, chronic alcoholism and drug abuse have also been associated with the development of cerebellar tremors. It is important to note that individuals suffering from this condition tend to experience symptoms when they are active or maintaining a specific posture.
