Frontal lobe syndrome

Frontal lobe syndrome For tumors located in the frontal lobe of the outbreak the following symptoms: - Psychiatric disorders: are found in most patients with tumors in the frontal lobe. Metastases and malignant gliomas are the most responsible for the occurrence of mental disorders. The frontal lobe plays a role in controlling personality, such as patients with an intracranial expansive process in the frontal lobe will show increased behavioral problems. At first interested affection. Patients become euphoric, were a permanent state of psychomotor excitation, shows an exaggerated optimism make pornographic jokes. Along with the development of tumor process, the state of euphoria is gradually replaced with a state of indifference, it alters your memory, lowers power of concentration, reduced performance at work.

The patient does not move, stay in one place and not only mobilizes the physiological needs. The conversation is remarkable lack of initiative, lack of interest in any subject. In advanced stages of disease when the tumor has grown much in size, meets decrease sphincter control.
- Epilepsy - this symptom occurs in more than half of patients with frontal lobe tumors. In some patients with epilepsy crisis begins adverse or generalized seizures. - Grand mall seizures are common in the tumor invades deep frontal lobe parenchyma. - Jacksonian seizures focused: they appear on the opposite half of the body affected cerebral hemisphere. These crises may be of interest strictly a particular member, superior or inferior, rarely hemicorpul all that interested. Sometimes seizures end leaves behind a transient paresis of the affected limb.
- Aphasia and clips: difficulty in speaking and writing is cursive. A feature of the aphasia and brain tumors agrafiei is that these disorders occur and evolve gradually, slowly, as the tumor increases in volume and affects more and more brain areas.
- Facial nerve paresis: paresis of VII nerve (or face) is the central type. It is accompanied by signs of pyramidal damage. Central type of facial palsy can be considered a pathognomonic sign for a growing tumor in the frontal lobe.
Other signs and symptoms that accompany brain tumors are located in the frontal lobe: motor disorders that become more pronounced with even more interested in how tumor motor area of the frontal lobe. Motor disorders usually occurs as a hemiparesis or hemiplegii affecting half the body opposite the brain hemisphere affected. In the frontal lobe tumors also meets forced grasping reflex. This reflex reaction is manifested by grabbing the last two fingers on each hand controlaterala when their daughter palm is stimulated by contact with an object. The reaction is involuntary and can not be stopped by the patient.
Cerebellar disorders are produced by damage dental Talamo-cortical pathways. Clinical manifestations of these disorders is materialized by cerebellar ataxia controlateral limb, hypotonia with reflex oscillation of opposite, opposing limbs dismetria adiadocokinezie (inability to make rapid alternative movements). Balance disorders occur relatively frequently and is manifested by gait and the static. Balance disorders arising in the context of a frontal lobe tumor called frontal ataxia Bruns. Also occur in most patients, impaired orientation in space, patients no longer recognize the house where they live, no longer recognize the street, etc..
