Hi
I understand your concern and admire your positive outlook.
If she studied up to 10th well then may be she is having borderline mental retardation.
patient with MR is prone to have behavior disturbance like crying,laughing, throwing etc.
They have lack of adaptive function of daily routine and easily forget task.
Frankly speaking there is no treatment which enhance her brain power or memory from Mental retardation.
Only thing help is behavior therapy and modification.
Proper parental counseling and learn how to deal with patient with MR is essential.
Behavior issues can be treated with medicines like carbamazapine or oxcarbamazapine.
Need to rule out other psychopathology if she has so please do consultation and get exact IQ of her and other psychiatric evaluation.
Psychiatrist will guide you how to deal and how to care such patients.
Happy to help you
Hope for the best.
Still have query then feel free to ask.
Thank you.
