Symptoms of Different Types of Epileptic Seizures
Epilepsy is a neurological condition that causes seizures. A person is said to have epilepsy if he experiences two or more seizures, a disorder in the electrical communication between neurons in the brain, separated by a period of 24 hours. The consequences of an epileptic seizure can vary from uncontrolled jerking movement to momentary loss of awareness. These can also vary in frequency, from several times in a day to only once in a year. Understanding epilepsy seizure symptoms is the first step in treating this disorder. Types of epileptic seizures and their symptoms Differentiating seizure types is important for causes, diagnosis, and treatment. Epilepsy seizure symptoms are broadly classified into two groups – focal seizures and generalized seizures. Focal seizures are the ones which initially affect only one hemisphere of the brain. There are four lobes in each hemisphere of the brain. The seizure symptoms vary based on where the seizure has occurred. This is further divided into two categories: Focal aware seizure – This affects only a small area of the brain and people experiencing this type of seizure remain conscious. The common symptoms include the following. A sudden feeling of fear, anger, anxiety Falling or moving sensations Altered sense of hearing Strenuous speech or incapable of speaking If asleep, hallucinations or illusions Focal impaired awareness seizure – This is associated with unilateral cerebral hemisphere and results in impairment of awareness. The common symptoms include the following. A feeling of déjà vu, a feeling that a person has lived through the present situation A feeling of euphoria or depersonalization Display of automatisms like, lip smacking or swallowing Generalized seizures – These are typically characterized by no apparent cause. Unlike focal seizures, it affects more or the whole part of the brain. This is further classified into the following types.
