The core symptom of Parkinson's disease is bradykinesia, which is a slowing and inflexibility of movement in daily activities. Shaking, also known as tremor, is a well-known symptom of Parkinson's disease, but the tremor of Parkinson's disease has its characteristics, that is, it is manifested as resting tremor, which is obvious when still, aggravated by mental stress, relieved when doing voluntary movement, and relieved when sleeping. disappear.
Most of the symptoms start from one upper extremity, which is manifested as shaking like "rubbing a pill". As the disease worsens, the legs, jaw and head may shake. It should be pointed out that not all shaking is Parkinson's disease, there are some conditions such as physiological tremor, essential tremor, etc., their incidence is much higher than Parkinson's disease.
Another important motor symptom of Parkinson's disease patients is muscle stiffness, which not only affects the limbs but also the facial expression muscles, so patients with Parkinson's disease will have reduced facial expressions, often called "mask face".
In addition, there are many motor symptoms, such as abnormal gait, patients with Parkinson's disease often show "small steps" when walking, leaning forward, lack of arm swinging back and forth, and difficulty in stopping. As the disease progresses, patients feel that their feet are stuck to the floor and have difficulty lifting, a condition known as "frozen gait," and often falls due to instability.
Frequent insomnia or early awakening, urgency to urinate, frequent urination, and frequent urination may be non-motor symptoms of Parkinson's disease. Here are four non-motor symptoms of Parkinson's disease to be wary of, experts say.
One is "the nose is not working". More than 90% of Parkinson's disease patients have symptoms of hyposmia, and many patients have been found to have hyposmia for many years at the time of consultation.
The second is "not sleeping well". It is understood that many Parkinson's disease patients have difficulty falling asleep, wake up frequently or early, excessive sleepiness during the day, and may scream, make noise, kick people, and beat people in their sleep, which seriously affects the sleep quality of patients.
The third is constipation. Patients often develop symptoms of constipation 10 or even 20 years before the onset of symptoms.
Fourth, anxiety and depression. Anxiety is mainly manifested as generalized anxiety and panic disorder; the incidence of depression is the highest, which can run through the entire course of Parkinson's disease.
