چکیده مقاله:

Focal epilepsies are characterized by seizure arising from a specific part (lobe) of the brain include frontal lobe, temporal lobe, parietal lobe and occipital lobe epilepsy.Focal epilepsy maybe treated with medication and occasionally with diet, nerve stimulation or surgery. Especially in the condition is due to a scar or other lesion in the brain.Frontal lobe epilepsy: Frontal lobe epilepsy is the term for recurring seizures beginning in the frontal lobe. Because the frontal lobe is responsive for planning, executing movement and personality. Frontal lobe epilepsy can have a dramatic effect on a patient’s quality of life. Frontal lobe seizures are often very brief and tend to occur at nights. They are typically with preserved awareness or impaired awareness and can quickly spread throughout the brain. Because there are so many connections between frontal and temporal lobe. It can be difficult to determine which section of the brain is being affected. Anticonvulsant drugs are the most first common choice for treatment if those do not control the seizures, surgery maybe an option. Temporal Lobe Epilepsy: Temporal lobe epilepsy is the term for recurring seizures beginning in the temporal lobe. The temporal lobes are areas of the brain that most commonly give rise to seizures. The mesial portion (middle) of both temporal lobes is very important in epilepsy - it is frequency the source of seizures and can be prone to damage or scarring. Because there are so many diverse functions either in or closely related to the temporal lobes, these seizures may have a dramatic effect on the patient’s quality of life. Seizures beginning in the temporal lobes may remain there, or they may spread to other areas of the brain. Depending on if and where the seizure spreads, the patient may experience the sensation of: Seizures beginning in the temporal lobes may remain there, or they may spread to other areas of the brain. Depending on if and where the seizure spreads, the patient may experience the sensation of:  A peculiar smell ( such as burning rubber) Strong emotions(such as fear)  Abdominal/chest discomfort  Automatic, unconsciously repeated movements  Staring  Loss of awareness Parietal Lobe Epilepsy: Parietal lobe is the section of the brain on the top and sides of the head. Known as the association cortex the parietal lobe is responsible for connecting meaning to the brain’s functions. It is here that the brain creates a visual image, that sounds are recognized as words, and that the sense of touch is associated with a particular object. In some ways, the parietal lobe is where perception meshes with physical reality. Parietal lobe epilepsy is very uncommon. Seizures staring in this area can cause sensory disturbance, such as heat, numbness or electrical sensations, weakness, dizziness, hallucinations, distortions of space and other symptoms. Occipital Lobe Epilepsy: Occipital lobe epilepsy is the term for recurring seizures beginning in the occipital lobe, the section of the brain in the back of the head that is primarily responsible for vision. Seizures beginning in the occipital lobe rare. These seizures can cause a person to experience flashing bright lights or other visual changes on the left side of his or her visual field ( if occurring in the right cortex), or on the right side ( if occurring in the left cortex) .
