What condition is characterized by periods of confused memory and involuntary movements of arms and legs?

The condition characterized by periods of confused memory and involuntary movements of arms and legs is epilepsy. This neurological disorder can lead to seizures, which are episodes of uncontrolled electrical activity in the brain. During these seizures, individuals may experience various symptoms, including confusion, loss of consciousness, involuntary movements, and memory disturbances.

In particular, certain types of epilepsy, such as generalized tonic-clonic seizures, are associated with convulsions and may also involve a postictal state, which is a period of confusion or altered awareness following the seizure. The involuntary movements of the arms and legs during a seizure are a hallmark of these episodes, making epilepsy the correct choice in this context.

While ADHD is a behavioral condition that affects attention and impulse control, dyslexia is a specific learning disability related to reading, and a fluency disorder pertains to speech. None of these conditions typically present with the combination of confused memory and involuntary movements in the same manner as epilepsy does.
