Hi I think it can be more serious. As you are not aware of it and you have injuries and history of
incontinence , you may be having seizures. Usually such seizure cause behavioural problems and they do not get diagnosed easily and leads to misdiagnosis. All you need is to
consult a psychiatrist and explain all symptoms along with past history. You should be started on treatment soon as these seizures increase the frequency of further seizures.
Take care
