Chorea is one of neurological disorders. It is an abnormal involuntary movement disorder in which there is a dance like movements of the body parts. There is a semi-directed, irregular movement which is not repetitive or rhythmic in nature but they seem like flowing from one muscle to the other. The patient often appears to be maladroit and restless. It not only affects body parts but can also create problems with speech, swallowing, posture and gait.
Chorea can be linked with numerous causes, some are temporary and some may be chronic. Few of the causes are bad immune system, genetic conditions such as Huntington`s disease, infections resulting in rheumatic condition, metabolic disorders, pregnancy etc.
Though chorea symptoms generally depend on the conditions causing it but the most common symptom is milkmaid grip. This looks like a person is holding a utensil with a thumb pointing upwards. The other symptom is like putting out the tongue unknowingly. The movements of the body parts can be fast or slow and the patient may appear to be writhing in pain and loses control over the body.
A thorough medical history and a clinical exam is to be conducted to diagnose chorea. A doctor should know when the symptoms begin, what makes them worse or better, is it hereditary or genetic and what medication the patient is on? If a doctor knows a complete history then he could decide for the laboratory tests.
As there are various types of chorea, its treatment is also dependent on which type of chorea the patient is suffering from. Like few can be treated with antibiotic and even chorea due to Parkinson`s disease has no cure. There are surgeries which help in curing or at least help in reducing the symptoms of chorea.
There should be precautions that should be taken at home. The patient may feel like falling. So he should wear non slip foot wears and there should be non-slip floor surfaces installed in bathrooms and on stairs to prevent injury cases.
Though there is no standard treatment but proper medication, home care, preventions and thorough diagnosis can help in coming out of it.
