Psychiatrists are usually qualified to assess both the mental and physical aspects of all psychological problems. People often seek psychiatric help for multiple reasons. The problems can be sudden being as simple as a panic attack, frightening hallucinations, thoughts of suicide, or hearing unidentified "voices." Or to treat a more long-term health issue, such as feelings of sadness, anxiousness or hopelessness that never seem to get lifted or issues in functioning meanwhile causing everyday life to feel distorted or spin out of control. As a physician, psychiatrists are capable of prescribing medication and can also order or perform complex medical laboratory and psychological tests that can provide a comprehensive profile of the patient's physical and mental state.
