Depressed - watch out for Parkinson's disease!

Depression may be a precursor to Parkinson's, scientists' conclusions from a survey in Europe. The survey found that over 80% of Parkinson's patients often suffer from depression.

Depression may be a precursor to the image of a anxiety-depressive disease . In a survey of 500 mild to moderate Parkinson's patients in France, Germany, Italy, Spain and the UK, researchers Rescue found 40% of patients rarely - or never - told doctors about their depression.

The researchers also found almost all patients who were frequent or occasionally had symptoms of depression. However, 49% said these symptoms were difficult to identify.

Patients said depression was almost the most common sign when they had motor problems. Meanwhile, two-thirds of the doctors surveyed said they considered other symptoms more important than depression.

Parkinson's disease experts say symptoms of depression are just as important as motor problems for patients with the disease.

Parkinson's disease is a degenerative disease of the nervous system. Approximately 10,000 people are diagnosed with the disease each year, with one in 20 wearing the disease less than 40 years old. The most common symptom of this disease is shaking hands and feet.
