Symptoms of frontal lobe tumor

Frontal lobe tumors generally grow slowly, a longer history of the early symptoms was not obvious in the course development process in addition to headache, vomiting, papilledema and other symptoms of high intracranial pressure, its major clinical symptoms and spirit, emotion, movement, speech, cerebellar coordinated movements and other factors.

1. Psychological symptoms of psychiatric symptoms can be found in other parts of the intracranial tumor, but due to the spirit of the symptoms of frontal lobe tumor even more pronounced and appeared earlier, the incidence is higher, especially when both sides of the frontal lobe is damaged more apparent. Psychiatric symptoms of frontal lobe tumor manifested mainly memory disorder and personality changes in such a situation is even more common in the bottom of the prefrontal and frontal lobe tumor. Patients with early symptoms usually manifested can not concentrate, impaired memory and understanding, in particular, a weakened significantly in recent memory, and much to save memory.

2. Seizures of frontal lobe tumor, epileptic seizures are often the first symptom, its occurrence rate is about 33.3%, of which 4 / 5 are without aura grand mal epilepsy, 1 / 5 of the limitations epilepsy. Tumor invasion and the prefrontal cortex area 6 and 8 zone, seizures more than a loss of consciousness, head and eyes turned to the contralateral lesion of the contralateral upper and lower limbs twitching upper lesion clearly the onset of a small number of patients is only at this point, but most of Ji to develop into a generalized grand mal.

3. Pyramidal symptoms of frontal lobe damage to the abdominal wall and the tumor when the lesion contralateral cremaster reflex and the concurrent weakening of the disappearance of tonic plantar flexion reflex, and often an early symptom, with the tumors continue to grow and the right motor area in violation of degree contralateral lesions, there may be increased muscle tone, tendon reflexes, hyperactivity, and is often accompanied by ankle clonus, wrist clonus patella clonus, and so on, finally, there may be contralateral lesions of varying degrees of paralysis, Babinski sign is a corticospinal tract lesion of a representative of the important signs, frontal cortex motor area of any part of the tumor can occur.

4. Motor aphasia patients with right hemispheric dominance, such as tumor invasion and left posterior inferior frontal gyrus Broca area may Zhiyuan moving aphasia. The clinical characteristics of the patient's lips and tongue to freedom of movement, able to understand other people's language, but can not use speech dialogue with people and articulation organs, although some activities and accessibility can be pronounced, but can not constitute a language. Minor damage to the patients often do not complete the movement for aphasia, the patient still capable to make an individual voice, but it can not constitute a word from the voice name, nor can they line up the necessary sequence of words often said that a typo or there is slow language pause, Stuttering behavior and thus these can be issued to individual voice is disorganized and can not incomprehensible. In severe cases completely lost the ability to speak.

5. Frontal lobe frontal lobe tumor of Freemasonry aphasia caused by ataxia, is due to the amount of - Bridge of brain - the cerebellum caused by beam damage. Anatomy of frontal lobe fibers reach the bridge on the back of the head, after pontine transverse fibers into the contralateral cerebellar peduncle, reaching the cerebellum dentate nucleus, thus the majority confined to red nucleus send fibers, a few from the red nucleus to the thalamic ventrolateral nuclear re-arrival of motor area, namely the so-called cerebellar cortex - cortical circuit, Therefore, frontal lobe tumor can be derived similar cerebellar ataxia. Frontal lobe tumors early, especially in the amount of highly tumor, if not accompanied by increased intracranial pressure does not produce movement disorders and will not come to a standstill.

6. Strong grasp reflex of exploration campaign the amount of damages the rear of the frontal lobe tumors, especially near the superior frontal gyrus precentral gyrus, due to loss of control of voluntary movements, when the object touches the fingers and hand contralateral lesions of the palm caused by fingers and palm of the hand when The buckling and seize objects cling phenomenon, known as the strong grip reflex; patient hands have been an object contacts the hand and upper extremity are moved towards the object, such as continuous contact with the palm of your hand, you can make it to the parties to explore the upper limbs, touched on this matter until the hold of this material, known as the groping movement strong grip reflex and explore the simultaneous movement on one side, often an important basis for diagnosis of frontal lobe tumor.

7. Other symptoms of frontal lobe tumors were located in or near the bottom when the amount of influence or oppression olfactory nerve, resulting in the loss of sense of smell, tumor suppression side of the back side of the optic nerve disease can occur with primary optic nerve atrophy contralateral arise due to increased intracranial pressure papilledema (Foster-Kennedy syndrome). Medial frontal lobe tumor patients was sometimes a sense of urgency urinary incontinence, or voiding, so that there is no choice locations panic urination, and even fecal incontinence pairs of frontal lobe tumor or tumor invasion and the precentral gyrus, and sometimes may appear reflex sucking reflex, or smack. The deep frontal lobe tumors can occur even extrapyramidal symptoms, showing that there is a slight tremor contralateral limb. Another frontal lobe tumor can occur even stupor, the patient can be maintained at a fixed state of a long time without fatigue; a small number of patients, there may be poor food, hyperactivity and other sexual function.
