大脑各叶症状群(The various lobes of the brain)
The various lobes of the brain
The brain is divided into the left and right hemispheres, and the cerebral hemisphere is divided into frontal, parietal, temporal, occipital and island leaves. A series of corresponding symptom groups can occur when each leaf of the brain is damaged. The lesion location, pathogen nature and progression of disease affect the symptom. In this paper, we discuss the symptom group of the brain, the third and fourth ventricle symptom group. And the disease that has this symptom group is identified.
Reference:
The frontal lobe symptoms group (frontal lobe syndrome)
The frontal lobe is located in the anterior part of the brain, and there are four major brain gyrus, namely the anterior cingulate gyrus and the frontal gyrus and the inferior frontal gyrus. Frontal lobule lesions are mainly caused by voluntary movement, speech, cranial nerve, plant nerve function and mental activity.
[etiology] can occur in the anterior cranial fossa, anterior cerebral artery, medial artery to frontal lobe, sinus infection, frontal lobe tumor and pituitary apoplexy.
[clinical manifestations]
Cranial nerve palsy: before the skull concave tumor or limited arachnoiditis, lesion side smell disorders, primary optic nerve atrophy and the side-view papillary edema, double side papillary edema, disease side eyesight drops can rapidly, or even disappear completely.
2. Motor disorder: an irritant lesion of the frontal lobe, which occurs on the side, lower limb or face; Jacksons epilepsy; General epileptic seizures; Paralysis.
3. Abnormal reflectance: anterior region lesion in frontal lobe, strong grip reflex on the side, reflection of grope, dog reflex and early appearance of lateral tension reflex, reflex of the lateral upper limb leli (Leri).
4. The frontal lobes ataxia: the frontal lobe lesion, half of the patients in the area appear to sit, walk, turn unstable, and easily tip to the lesion.
5. Motor aphasia: complete motor aphasia
