Parkinson’s disease is a disorder of the central nervous system<\/a> caused by the destruction of nerve cells. It mainly affects movement control and is most commonly manifested by hand tremors. Although there is no cure for the disease, there are treatments that can help relieve symptoms and support patients. Find out more in this article.<\/p>

WHAT IS PARKINSON’S DISEASE?<\/h2>

Parkinson’s<\/a> disease is one of the most common neurodegenerative diseases after Alzheimer’s disease. It is characterised by the progressive degeneration of a specific population of nerve cells, particularly the dopamine neurons in the brain.<\/p>

This neurological disease affects the dopaminergic neurons in the area of the central nervous system known as the substantia nigra. These nerve cells gradually degenerate, leaving patients disabled over time.<\/p>\t\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

There are millions of cases of Parkinson’s disease worldwide. It is the cause of many disabilities in older people, especially men. However, it is women who have the best chance of survival. The situation is getting worse as the population ages.<\/p>

Even if the disease is incurable for the time being, it is important to consult a specialist neurologist. He or she will analyse the patient’s condition and prescribe treatments to alleviate the motor symptoms.<\/p>

The three stages of Parkinson’s disease are as follows:<\/p>

Stage 1<\/strong>: \u00a0Early signs of PD include subtle changes in walking, balance, speech and facial expressions.<\/p>

Stage 2<\/strong>: In stage 2, the symptoms of PD become more pronounced. You may have difficulty walking or start to have problems with your hands. You may also have trouble sleeping because you can’t relax your muscles at night.<\/p>

Stage 3<\/strong>: In stage 3, you’ll have severe problems walking and getting around. Your speech may slow down and become slurred or blurred and difficult to understand.<\/p>\t\t\t\t\t\t\t<\/div>\r\n\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div><\/div>\r\n\t\t<\/section>\r\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div><\/div>\r\n\t\t<\/main>\r\n\t\t\t\t

Parkinson’s disease progressively destroys dopaminergic nerve cells. Once 50-70% of these nerve cells have been affected, motor symptoms begin to appear. This is the time to see a specialist for diagnosis.<\/p>

The main signs of the disease can be subtle, but the earlier they are treated, the less damage is done. They include tremor, fatigue, slowness of movement (akinesia), difficulty concentrating and muscle stiffness (muscular hypertonia).<\/p>

Other problems can also occur, such as digestive problems, depression, sleep disorders, memory loss… In any case, the pathology develops very slowly and varies from patient to patient. Until now, the causes have not been identified.<\/p>

Parkinson’s syndromes are often divided into three groups:<\/p>
