What does deficiency in brain chemicals mean?

Q: My 48 years old husband weighs 48 kg and is 152 cm tall. He has recently been diagnosed with deficiency in brain chemicals. What does it mean? Is it curable? If yes, what are the treatment options available?

A:The origin of some disturbances of thought and behaviour - and anxiety, nervousness are such disturbances - are now believed to follow imbalances in chemicals within the brain. A relative deficiency in some chemicals can spark off abnormal behaviour.The best person to advise you on treatment of such imbalances of brain chemicals, side effects of treatment and other relevant details is the psychiatrist. I suggest you consult one in the teaching hospital nearest your home.
