The most common seizure experienced by older adults (66.2%) is the complex partial seizure , which is sometimes called a temporal lobe seizure and is accompanied by impaired consciousness.
The most common acquired etiologies of new-onset epilepsy and seizures in the elderly include cerebrovascular diseases, primary neuron degenerative disorders associated with cognitive impairment, intracerebral tumors, and traumatic head injury.
“When older adults have a seizure , their symptoms may in fact be mistaken for dementia, including Alzheimer’s disease, depression or just normal aging ,” Dr. Alexopoulos says. Seniors tend to develop focal epilepsy , which impacts only a small portion of the brain.
Like other kinds of seizures , absence seizures are caused by abnormal activity in a person’s brain. Doctors often don’t know why this happens. Most absence seizures are less than 15 seconds long. It’s rare for an absence seizure to last longer than 15 seconds.
Seizures take on many different forms and have a beginning (prodrome and aura), middle (ictal) and end (post-ictal) stage .
These EEGs use video to capture seizure activity. The EEG may show abnormalities even if the seizure does not occur during the test. However, it does not always show past abnormalities related to seizure .
Absence seizures are a type of epilepsy . They aren’t normally harmful, and most children grow out of them by puberty. But, you should talk to your child’s pediatrician because, untreated , they can affect your child’s life and learning.”
Epilepsy can begin at any time of life, but it’s most commonly diagnosed in children, and people over the age of 65 . Some children with epilepsy will outgrow their seizures as they mature, while others may have seizures that continue into adulthood.
Thus some people with epilepsy may be at a higher risk of developing dementia , while individuals with some forms of dementia , particularly Alzheimer’s disease and vascular dementia , are at significantly higher risk of developing epilepsy .
The medicines most commonly used for absence seizures include ethosuximide (Zarontin), lamotrigine ( Lamictal ), valproic acid ( Depakene ), or divalproex sodium ( Depakote ). In about 7 out of 10 children with absence seizures, the seizures may go away by age 18. If this happens, medicines may not be needed as an adult.
Absence seizures involve brief, sudden lapses of consciousness. They’re more common in children than in adults . Someone having an absence seizure may look like he or she is staring blankly into space for a few seconds. Then, there is a quick return to a normal level of alertness.
Tonic, Clonic and Tonic-Clonic (Formerly called Grand Mal) Seizures .
The outlook is very good. Most children with absence epilepsy eventually outgrow the condition without complications. With proper treatment , the child can have a normal life at school and at home. In most cases, there is no long-term effect on brain development, brain function or intelligence.
Children with absence seizures often outgrow the condition. Absence seizures can continue, however. Some patients progress to longer or more intense seizures .
Generally speaking, typical absence seizures have no discernible cause. Atypical seizures are similar to typical seizures , except they tend to begin more slowly, last longer (up to a few minutes), and can include slumping or falling down. The person may also feel confused for a short time after regaining consciousness.
