Henry Wachtel, 19, was arraigned Monday on murder charges.
Police say his mother, 63-year-old Karyn Kay, called 911 from their apartment last Tuesday to say her son was having a seizure.
The defense blames Wachtel's epilepsy medication for his violent reaction.
Kay was a published author and a film maker who taught at LaGuardia High School and Pratt Institute.
Her movie "Call Me" was released in 1988 to positive reviews.
