Seizure Causes in Older Adults
Seizures in adults over 60 years old often stem from acquired brain injuries or conditions more prevalent in this age group. Common causes include:
- Cerebrovascular disease: Strokes (ischemic or hemorrhagic) are a leading cause of new-onset seizures in the elderly.
- Central nervous system neoplasia: Primary brain tumors or metastases can cause seizures.
- Degenerative disease: Conditions like Alzheimer's disease or other dementias are associated with increased seizure risk.
Identifying the Exception
The question asks to identify the cause that is less common or not typically considered a primary cause of new-onset seizures specifically in the older adult population (>60 years) compared to the others listed.
Mesial temporal lobe sclerosis (MTLS) is a common cause of epilepsy, particularly refractory epilepsy, but it is typically diagnosed earlier in life, often following prolonged febrile seizures in childhood. While it can persist into older age, it is not considered a frequent *new* cause of seizures in the over-60 demographic relative to cerebrovascular events, tumors, or neurodegenerative processes.
Therefore, Mesial temporal lobe sclerosis is the exception among the listed common causes of seizures in adults older than 60 years.
