According to the International League against Epilepsy (ILAE), seizures are defined as excessive or synchronous neuronal activity in the brain that is manifested as signs or symptoms. As per the classification system by the American Clinical Neurophysiology Society, seizures can be classified into electroclinical (clinical signs of a seizure ...
The symptoms vary widely, as do the treatments. Central nervous system tumors are the most common forms of pediatric cancer. Brain tumors are the most frequent and have the highest mortality. [4] Some disorders, such as substance addiction, autism, and ADHD may be regarded as CNS disorders, though the classifications are not without dispute.
Sometimes the convulsion can be caused by genetic defects or brain tumors. [1] Convulsions can also occur when the blood sugar is too low or there is a deficiency of vitamin B6 (pyridoxine). The pathophysiology of convulsion remains ambiguous. [5] Convulsions are often caused by epileptic seizures, febrile seizures, non-epileptic seizures, or ...
Focal seizures affect a specific area of the brain, not both sides. [13] It may turn into a generalized seizure if the seizure spreads through the brain. [3] [13] [8] Consciousness may or may not be impaired. [3] [5] The signs and symptoms of these seizures depends on the location of the brain that is affected. Focal seizures usually consist of ...
Seizures, especially during the night, are a heavily weighted indicator of LKS. The prevalence of clinical seizures in acquired epileptic aphasia (LKS) is 70–85%. In one third of patients, only a single episode of a seizure was recorded. The seizures typically appear between the ages of 4 and 10 and disappear before adulthood (around the age ...
Epilepsy is a neurological condition of recurrent episodes of unprovoked epileptic seizures. A seizure is an abnormal neuronal brain activity that can cause intellectual, emotional, and social consequences. Epilepsy affects children and adults of all ages and races, and is one of the most common neurological disorders of the nervous system. [1]
The signs and symptoms of Serotonin Syndrome include: Agitation or restlessness. Insomnia. Dilated pupils. Loss of muscle coordination or twitching muscles. Muscle rigidity. Tremor. Heavy sweating ...
Reversible cerebral vasoconstriction syndrome (RCVS, sometimes called Call-Fleming syndrome) is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. [1] Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1]
