Half a year ago, 56-year-old Mr. Chen was noticed by his family that his left hand occasionally shook slightly, but he didn't feel anything and didn't care. Not long ago, he caught a cold, and the symptoms such as nasal congestion and runny nose gradually subsided after self-**, but he has always felt soreness and weakness in his limbs, and his movements have become a little sluggish. After a few days, the family noticed that the shaking of his left hand had become more frequent and much larger. The family immediately took Mr. Chen to the Jianhua Campus of Shijiazhuang People's Hospital for medical treatment, wanting to find out the reason.
Li Jiamin, who received Mr. Chen's illness from the Fifth Department of Neurology, carefully observed his hand trembling and checked his muscle tone, suspecting that Mr. Chen was suffering from Parkinson's disease, but considering that Mr. Chen had not reached the average age of onset of 60 years old and his muscle tone was not high, his symptoms were not very typical, so he arranged for Mr. Chen to undergo ultrasound examination of the substantia nigra of the midbrain to further determine whether he had Parkinson's disease.
Ultrasound examination showed that Mr. Chen's midbrain substantia nigra had patchy hyperechogenicity, the echo intensity was grade III positive (grade and above is abnormal), and the unilateral substantia nigra hyperechoic area exceeded 020cm2。Combined with the results of ultrasound, Li Jiamin diagnosed that Mr. Chen was indeed suffering from Parkinson's disease and was given corresponding drugs**. After a period of time, Mr. Chen's symptoms such as hand tremors, limb weakness, and slow movement were gradually alleviated, and his quality of life was greatly improved.
At present, Parkinson's disease is an irreversible and irreversible disease, but through early active and standardized disease, symptoms can be controlled, the progression of the disease can be delayed, and the quality of life can be improved, so early detection and early development are of great significance. With the "black technology" of ultrasound in the substantia nigra of the midbrain, it provides great help for the early detection and prevention of Parkinson's disease. Come and learn about this "black technology" with Yang Xiaoqing, director of the first ultrasound department.
Parkinson's disease is caused by the degeneration and death of dopaminergic neurons in the substantia nigra of the midbrain, resulting in a significant decrease in the amount of DA in the striatum. Therefore, the "Diagnostic Criteria for Parkinson's Disease in China" takes ultrasound of the substantia nigra of the midbrain as one of the supporting criteria for the diagnosis of Parkinson's disease. This "black technology" is to use an ultrasound probe to scan the substantia nigra of the midbrain through the temporal window, and judge whether there is an abnormality according to the strength of its echo signal, so as to provide neurologists with a basis for diagnosing and differentiating diseases, which can reduce the misdiagnosis or missed diagnosis of patients who are in the early stage of the disease, the symptoms are atypical, and the diagnosis is difficult, so that Parkinson's disease has nowhere to hide.
Popular science time. 1What is Parkinson's disease?
Parkinson's disease is a neurodegenerative disease common in the elderly, with an average age of onset of about 60 years old, and is the "third killer" of geriatric health after malignant tumors and cardiovascular and cerebrovascular diseases. Its symptoms can be divided into motor symptoms and non-motor symptoms, and generally non-motor symptoms appear 5-10 years earlier than motor symptoms.
The main manifestations of non-motor symptoms are: hyposmia, constipation, urination disorders, sexual dysfunction, orthostatic hypotension, cognitive impairment, depression, sleep disorders, mental disorders, pain, etc.
The main manifestations of motor symptoms are: bradykinesia, resting tremor and muscle rigidity, of which bradykinesia is the most core symptom, and sometimes posture and balance function are also affected. At the time of presentation, the above symptoms are often described as "walking in small broken steps, walking forward", "writing gets smaller and smaller", "speaking in a low voice, slow dry activities, expressionless", "finger rubbing like shaking when quiet", etc.
2Who needs ultrasound of the substantia nigra of the midbrain?
1) If you have symptoms related to Parkinson's disease, such as bradykinesia, tremor, and muscle tension.
2) When Parkinson's disease is suspected and it is necessary to distinguish between them.
3) Someone in the family has Parkinson's disease and needs to be screened.
3. Diagnostic criteria for ultrasound of the substantia nigra of the midbrain.
The substantia nigra of the midbrain resembles a black butterfly and is classified into the following 5 levels according to the intensity of the echo:
Grade: Homogeneously distributed hypoechoic;
Grade: Scattered in punctate, thin lines slightly more echoic;
Grade: Echogenic in patchy form, lower than basal cistern echo
Grade: Echo is patchy and enhanced, equal to basal cistern echo;
Grade: Echo is patchy and enhanced, higher than basal cistern echo.
The grade is normal, the echo intensity of the substantia nigra in the midbrain is positive, and the hyperechoic area is measured, and the unilateral substantia nigra hyperechoic area is 020 cm2, or a bilateral substantia nigra hyperechoic area and 7% of midbrain area, suggests Parkinson's disease.
