*Other conditions that can cause symptoms similar to those of Parkinson's disease are:
- Essential tremor (name by which types of tremor are grouped without apparent pathological significance and especially hereditary), which has no symptoms other than tremor fine and fast. Can occur before the age of 25 years;
- Parkinson's syndrome met super nuclear progressive paralysis (a heterogeneous degenerative disorder involving damage to nerve cells in the brain, the cerebellum or basal ganglia) and multiple system atrophy (proposed term variable combination of the following disorders: dysfunction of the autonomic nervous system , extra-pyramidal signs, ataxia that occurs, especially in adulthood);

- Alzheimer's disease. Confusion and memory loss similar to those in early stages of Alzheimer's disease does not appear until late stages of Parkinson's disease;
- Central nervous system lesions;
- Various thyroid disorders;
- Liver disease;
- Central nervous system infections (ex encephalitis);
- Brain tumors;
- Myocardial infarction;
- Carbon monoxide poisoning;
- Intoxication by heavy metals (such as manganese);
- Psychiatric disorder.



Certain medications (such as antipsychotics and certain medications used to treat high blood pressure) may also give similar Parkinson disease symptoms. Other symptoms that may appear in this condition can include depression and sexual dysfunction. These issues should be discussed with your doctor.

*Risk factors
Risk factors in this disease are difficult to identify because the disease is not known. Advanced age is the only known risk factor for Parkinson's disease (not included early-onset Parkinson's disease). Most debut after 50 years, although disease can occur in people between 30 and 50 years and even, in rare cases, the youth.
A very small number of people who have been diagnosed with this disease have a close relative suffering from Parkinson's disease symptoms. It seems that a family history of Parkinson's disease significantly increases the risk of disease from a family member. With family cases early onset Parkinson's disease can be an important risk factor in illness and other family members, but it is a rare form.
Some studies have shown that prolonged exposure to certain environmental factors, such as pesticides, chemicals, using water from wells can increase the risk of disease, but until now this has not been demonstrated. There are many conditions that can develop Parkinsonism (a group of symptoms that include tremor, muscle rigidity, slower movements and balance disorders).



And evolution of the disease symptoms may vary greatly from person to person. There is no known cure for this disease. However, medicines, surgery, exercise and lifestyle changes can reduce some symptoms.
Emotional state can affect disease symptoms. Anxiety, nervous tension and sadness can the evolution of the disease and symptoms. Relaxation usually reduces symptoms. In a stressful time a person with Parkinson's disease can have a "paradoxical outburst." This has as result a time when people affected by Parkinson's symptoms and no longer can move and move normally.
