Diagnosis for Parkinson disease can be difficult because the symptoms exhibiteds closely resembles those presented by other diseases. About 8%-36% of all positive diagnosis done by physicians for the disease are wrong and they usually turn out not to be Parkinson disease. The signs usually appear in some part of the body initially and spread to the other parts of the body with time. The most noticeable first symptom is a feeling of fatigue and general malaise. The person feels tired very easily and experiences periods of sleepiness during the day. The people will experience difficulty in writing and speaking, coordinating these activities may be a bother to them.
People may also experience tremor and rigidity which are early symptoms of Parkinson’s disease. The tremor usually occurs when the person is at rest. The people may experience the tremor in the leg or on the hand and it usually stops when they do an activity. The tremors spread to other parts on one side of the body including the face and other parts of the body; the person may also experience internal tremors. When the tremors set in, what follows through is rigidity in the affected parts. The muscles in the body contract in jerk like motions and render the people unable to use the particular parts of the body.
The person may also experience a general feeling of fatigue and lack of concentration. The sleeping disorders come about from the general need to go to urinate during the night or may result from difficulty in breathing when sleeping. Another early symptom of Parkinson that may be experienced is problem with balance and posture; they fall too often and may find themselves slouching too far forward when walking. Another early sign of Parkinson disease are problems related to gastrointestinal parts of the body. The face of the people may become mask-lie with little expression. Patients may not be able to portray their emotions through their facial expressions because they have very limited control over them.
During the initial stages of the disease, a person may also start speaking in a slurred voice; initially the person may mumble over words and speak in a soft voice. The people will also be more withdrawn and less social; this a personality change disorder. In the initial stages, the person may experience some feeling of vague paranoia and extreme fear which may be overlooked. A patient may also occasionally experience panic attacks and extreme nervousness for no apparent reason. A lack of a sense of smell is also experienced for people with Parkinson; the disease initially also kills the function of the brain to discern smells. Many people who are prone to the disease also gain a lot of weight during their midlife years -- usually between 40 and 50.
