U must follow up well to the psychiatrist for betterment of the patient. For all over the health issue of the patient u must consult a good homoeopathic doctor for treatment. Along with allopathic treatment homoeopathy can do wonderful results. Ankylosing spondylosis is best treated in homoeopathy. Mental disorder is also treated well in homoeopathy. If patient is now on depression or low mood then u also consult psychologist for better mental health.Counselling sessions and Behaviour therapy etc do fine results in depression. Always support ur patient. Help him to rise his self confidence. Family support and love and care are the basic factors yo treat depressed patients. Thank you...
