are there any related illnesses or ailments to parkinson's disease
Parkinson's disease Parkinson's disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system.[1] The symptoms generally come on slowly over time.[1] Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking.[1] Thinking and behavioral problems may also occur.[2] Dementia becomes common in the advanced stages of the disease.[2] Depression and anxiety are also common, occurring in more than a third of people with PD.[2] Other symptoms include sensory, sleep, and emotional problems.[1][2] The main motor symptoms are collectively called "parkinsonism", or a "parkinsonian syndrome".[4][8]
Somatic symptom disorder Symptoms are sometimes similar to those of other illnesses and may last for years. Usually, the symptoms begin appearing during adolescence, and patients are diagnosed before the age of 30 years.[7] Symptoms may occur across cultures and gender.[6] Other common symptoms include anxiety and depression.[6] However, since anxiety and depression are also very common in persons with confirmed medical illnesses,[8] it remains possible that such symptoms are a consequence of the physical impairment, rather than a cause. Somatic symptom disorders are not the result of conscious malingering (fabricating or exaggerating symptoms for secondary motives) or factitious disorders (deliberately producing, feigning, or exaggerating symptoms).[9] Somatic symptom disorder is difficult to diagnose and treat. Some advocates of the diagnosis believe this is because proper diagnosis and treatment requires psychiatrists to work with neurologists on patients with this disorder.[6]
