OVERVIEW
Overview
Angular gyrus syndrome is a group of syndromes characterized by inability to write and calculate, loss of finger recognition, and left and right disorientation. The lesions are usually located in the parieto-occipito-temporal junction of the primary hemisphere, the left parietal angular gyrus and the second occipital gyrus. The manifestations are left and right disorientation and lack of discrimination; dysrecognition, dyslexia, dyscalculia, amnesic aphasia and dysgraphia; right ipsilateral hemianopsia, loss of optokinetic nystagmus, visuospatial disorientation; and incomplete paralysis of some of the spreading nerves.
Whether medical insurance
yes
Department
Neurology, Neurosurgery
Synonyms
Gerstmann syndrome
Clinical Symptoms
Loss of finger recognition, inability to calculate, inability to write, left and right disorientation, etc.
Harm
Often affects social adjustment and communication skills.
Tests
CT, magnetic resonance imaging (MRI), etc.
Diagnosis
Diagnosis is made on the basis of medical history, loss of finger recognition, inability to calculate, inability to write, left and right disorientation, and imaging tests.
Treatment principle
Treatment of the primary disease is the mainstay, and drugs to promote brain function, reasonable rehabilitation can be given, and surgery can be performed if necessary.
Curability
Aggressive treatment can improve the symptoms, whether cure depends on the primary disease.
Dietary advice
Balanced nutrition and reasonable diet.
Etiology
Etiology
Caused by cerebrovascular lesions, tumors, trauma, inflammation, poisoning, brain atrophy, etc.
Symptoms and Diagnosis
Typical symptoms
Speech comprehension and expression are normal, object and spatial cognition exists, and the following 4 symptoms occur in the absence of sensory-motor and intellectual and other disorders:
1. Inability to recognize fingers
Loss of ability to name and recognize each finger of one’s own or another person’s hands; in most cases, the thumb and little finger can still be called and recognized, but the remaining 3 fingers cannot be recognized and called. The patient can imitate the movements of the examiner’s fingers.
2. Inability to calculate
The patient cannot calculate with fingers, cannot read and write out numbers, cannot add, subtract, multiply and divide mentally, and has unclear concepts of time, weight, volume, distance, etc. Although the patient can sometimes do simple arithmetic, he or she cannot do it mentally. Although sometimes can be simple mental arithmetic, but the written calculation, because can not grasp the spatial location, so often wrong line and number of bits, the location of the written calculation is often biased towards the low end, but for the concept of number and number can be well understood.
3. Inability to write (dysgraphia)
Inability to control the size and position of writing, often writing wrong words or non-existent words, similar words, inverted words (mirror writing), wrong vertical and horizontal strokes of words, omission of words, grammatical errors, semantic errors, meaningless words, and consecutive words of the same character, but the concept of words is still preserved.
4. Left-right orientation disorder
The child is not only unable to understand and recognize his/her left and right sides, but also unable to recognize spatial orientation, for example, when he/she is asked to stretch his/her right or left hand, or to lift his/her right or left foot, he/she is unable to recognize left and right, and is unable to recognize left and right in shoes or gloves.
It is rare to see all four of these severe symptoms at the same time, but at most two to three of them are present, and they are often accompanied by aphasia or structural dysfunction.
Diagnostic basis
1. History of cerebrovascular disease or head trauma.
2. Typical manifestations such as loss of finger recognition, inability to calculate, inability to write, left and right disorientation.
3. Parietal or temporal lobe lesions can be seen in CT and MRI.
Treatment
Treatment policy
Treatment of primary disease, reasonable rehabilitation, surgery if necessary.
Drug treatment
According to the cause of the disease and the symptoms, choose the appropriate drug treatment.
Surgery
If there are cerebrovascular lesions or tumors, surgery can be performed if necessary.
Other treatments
On the basis of treating the primary disease, actively carry out rehabilitation therapy to improve the quality of life.
Prognosis
The prognosis depends on the primary disease. Those caused by ischemic cerebrovascular lesions have a good prognosis after active treatment.
Nursing care
Daily care
1.EnvironmentMaintain indoor air circulation, warmth, and sufficient sunshine; improve the living environment damp, dark and other adverse conditions.
2. Rest and activities: live a regular life, ensure sufficient rest and sleep; encourage patients to take care of themselves as much as possible within the range of their activity endurance.
3.Psychological care: comfort and encourage the patient, help to establish confidence in overcoming the disease and stabilize the patient’s mood.
Dietary care
Balanced nutrition and reasonable diet.
