Parkinson's disease, also known as tremor paralysis, is a common neurodegenerative disorder. The cause of Parkinson's disease is not yet clear, but it may be related to several factors, such as aging, genetics, and environmental factors. Since Parkinson's disease is the result of multiple factors, including abnormal protein aggregation, oxidative stress, mitochondrial damage, inflammation, and excitotoxicity of glutamate, these elements lead to the loss of dopaminergic neurons in the substantia nigra of the midbrain and a reduction in dopamine neurotransmitters in the striatum. This ultimately results in the patient's bradykinesia, muscle rigidity, and resting tremor.

What are the symptoms of Parkinson's disease?

Parkinson's disease is a relatively common disease among the elderly, causing significant inconveniences in their daily lives and making it difficult for them to move. Moreover, this disease progressively worsens. Overall, the symptoms of Parkinson's disease primarily include noticeable movement slowness; patients perform tasks very slowly, such as wrapping dumplings or rolling dumpling wrappers, which are done clumsily and slowly. They also dress, turn over in bed, and tie shoelaces very slowly. Additionally, there are evident symptoms such as resting tremors and muscle rigidity. Some people may experience a panicked gait, rushing forward and unable to control their steps. Patients might also experience severe constipation, a reduced sense of smell, and some have sensory abnormalities in their limbs.

What is needed to diagnose Parkinson's disease?

The definitive diagnosis of Parkinson's disease primarily relies on the patient's medical history, clinical manifestations, and a thorough physical examination by a neurologist. If the onset of the disease is very slow, presenting with symptoms such as bradykinesia and tremors, and the neurologist observes heightened muscle tone and slow movements during the examination, a high suspicion of this disease is warranted. Additionally, certain auxiliary tests are necessary, commonly including: First, testing the patient's sense of smell is crucial, as a reduced sense of smell is very important in diagnosing Parkinson's disease. Second, some brain MRI scans are needed mainly to exclude some secondary Parkinson's syndromes. Third, a brain PET-CT scan can be performed to examine the functionality of the striatum. Furthermore, an ultrasound of the substantia nigra in the midbrain can also be conducted, which holds significant value in assisting the diagnosis.

What to do about constipation in Parkinson's disease?

Among Parkinson's disease patients, constipation is a very common clinical symptom. In fact, many patients have experienced constipation for many years before the onset of Parkinson's disease symptoms, mainly due to the impact on some autonomic nerves in the intestines. For Parkinson's patients experiencing constipation, the main suggestions are: First, be sure to drink plenty of water. Drinking enough water can sufficiently lubricate the intestines and facilitate smoother bowel movements. Second, be sure to eat plenty of fresh vegetables and fruits. Vegetables and fruits are rich in vitamin C and can promote gastrointestinal motility. Additionally, it is recommended for patients to eat more bananas, as bananas have an evident laxative effect. Also, eat less of certain foods that can dry out the stool, such as sweet potatoes and chestnuts. If necessary, patients can be given laxative medications, and if bowel movements are extremely difficult, enemas can also be administered.

How to medicate for the rigidity in Parkinson's disease?

Parkinson's disease presents with rigidity, mainly due to increased muscle tone and muscle rigidity, which is a very important clinical manifestation of Parkinson's disease. The medications used for rigidity in Parkinson's disease mainly include the following types. The first type is dopamine receptor agonists, which can improve limb muscle rigidity to some extent and delay the progression of the disease. The second type of medication is levodopa preparations, which are currently the gold standard for treating Parkinson's disease. Many patients experience significant clinical improvement after taking the medication. The third type of medication includes some anticholinergic drugs. These drugs are particularly effective against tremors and also have some effect in improving rigidity. Medication for Parkinson's disease must be taken under the guidance of a doctor. It is also important to note that levodopa preparations should be taken on an empty stomach or two hours after a meal for better efficacy.
