General or Other | General Practice | Tremor (Symptom)
Tremor is an abnormal movement characterized by involuntary rhythmic oscillations of a body part (Member, trunk, face). Tremor can distinguish different varieties depending on their circumstances of occurrence: Resting tremor persists when the subject is immobile - seated or stretched. It is a mark of Parkinsonian syndrome and Parkinson disease. Tremor achieves especially at extremities, predominantly hands (movement to fragmentation of bread). Postural Tremor or shaky attitude than when the subject is not hold a position, for example, if asked to keep arms extended in front.
Tremor is generally caused by problems in parts of the brain that control muscles throughout the body or in particular areas, such as the hands. Neurological disorders or conditions that can produce tremor include multiple sclerosis, stroke, traumatic brain injury, and neurodegenerative diseases that damage or destroy parts of the brainstem or the cerebellum.
The most common is the physiological tremor, an emotion caused or contributed to the exciting (coffee). Another form is the shake caused by taking a drug (tricyclic antidepressants, lithium) or disease (Basedows disease excess thyroid hormones, blood sugar, reducing blood glucose levels, chronic alcoholism).
In other cases, it is part of a syndrome of cerebellum (hindbrain touch or nerve pathways are in connection with it). Essential tremor is the most common type of tremor. Generally occurs when there is a problem with the nerves supplying certain muscles information. However everyone has essential tremor, only the movements are so small that they are hard to spot. Specific causes of occurrence of tremor what makes are unknown. Some research suggests that the cerebellum, the brain that controls muscles movements, does not work in patients suffering from essential tremor. It can occur at any age but is most common in people over 65 years. Can also occur with other neurological diseases, including dystonia, Parkinson and certain inherited diseases, suggesting that genes play a very important role. .
