We all know that Parkinson’s is a common disease among middle-aged and elderly people. I often hear people ask me why the elderly are prone to Parkinson’s? What are the causes? Here I will briefly introduce you why the elderly are prone to Parkinson’s disease, I hope it will help you. 1, family heredity: medical doctors in long-term practice found that Parkinson’s disease seems to have a tendency to gather in families, families with Parkinson’s disease whose relatives have a somewhat higher incidence than the normal population. 2, Parkinson’s patients mostly have an acute history of poisoning and gradually develop signs of diffuse brain damage, including generalized rigidity and mild tremor. 3, patients with cerebral atherosclerosis leading to multiple lacunar cerebral infarcts in the brainstem and basal ganglia, affecting the nigrostriatal dopamine striatal pathway can appear Parkinson’s syndrome. 4, environmental factors: epidemiological findings found that there are regional differences in the prevalence of Parkinson’s disease, so it is suspected that there may be some toxic substances in the environment that damage the neurons of the brain. 5, ageing: Parkinson’s occurs mainly in middle-aged and elderly people, and the onset is rare before the age of 40, suggesting that old age is related to the onset. Studies have found that since the age of 30, the nigrostriatal dopaminergic neurons, tyrosine oxidase and dopa decarboxylase activity, and striatal dopamine transmitter levels gradually decrease with age. However, only a few elderly people suffer from this disease, indicating that physiological dopaminergic neuronal metamorphosis is not sufficient to cause the disease, and aging is only a contributing factor to the development of the disease. 6, infection: encephalitis, craniosynostosis can appear after the syndrome, such as type A encephalitis, mostly in the healing period of several years of latency, slowly appear serious and lasting PD syndrome. 7, drugs: taking antipsychotic drugs and tricyclic antidepressants poisoning and other causes of clinical symptoms or pathological changes, suspicious to produce symptoms similar to Parkinson’s, some can disappear completely after stopping the drug. 8, poisoning: such as carbon monoxide, manganese, mercury, cyanide poisoning, in the north gas poisoning is more common. Patients mostly have an acute history of poisoning, and later gradually appear signs of diffuse brain damage, including generalized tonicity and mild tremor. The above is the introduction of the causes of Parkinson’s disease, I believe you all understand it. If you are around people suffering from Parkinson’s patients must go to treatment in a timely manner, do not delay again and again and lead to serious deterioration of the disease, but also cause some hindrance to the body.
