Seizure Medications
Seizure medications such as Topamax can induce dementia-like symptoms as the purpose of the drugs is to block out certain brain signals which can lead to seizures. And unfortunately, long-term use of these drugs can also increase the chances of developing dementia at a later point.
The fact of the matter is, depending on the condition, you may need to be on these drugs for the long-term – if not, for life. The best thing you can do if that is the case is to keep your mind as stimulated as you can to help counteract the effects.
