Hello, First of all,ADHD appears in the childhood period and may continue to the adulthood period,if the patient does not take the medical treatment. Second,PTSD occurs after a tough situation the patient faces in his life. Third,depression symptoms can be similar to some symptoms of ADHD and PTSD. For example,depression affects our concentration and attention in daily activities,but this does not mean the patient with depression has ADHD. The patient with depression cannot enjoy his/her life and he /she always feels sad,but this does not mean the patient has PTSD. Fourth,the bipolar disorder means the patient has a period of hyperactivity,irritability and grandiose for one week then he has a period of depression and he/she experience the two periods one after another. Fifth,the medical treatment is not sufficient and may cause side effects to you,so you need a psychological treatment. Sixth,the healthy diet which is rich in vitamin B complex and folic acid can alleviate the symptoms of depression and anxiety.Moreover,too much saturated fat and too much salt in diet can make the symptoms of depression worse. Finally,the hormonal therapy for contraception,replacement therapy or irregular menses in women can make the symptoms of depression and anxiety worse. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Dr/Mustafa
