Memantine Might cause daytime sleepiness- consider changing to night If using in the morning- ? for behaviour changes If someone has seizures - some neurologists might try to avoid, again need to take all aspects into account Sodium Valproate Used for behaviour changes Can cause Parkinsonism like symptoms - rigidity, stiffness, sleepiness [watch out for swallowing difficulties] Some neurologists might recommend Keppra, if Valproate is used for seizures.
