<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello my name is Gary and i have becoming more tired unable to focus and have lost some of my motor controls at random moments. I have also had some memory trouble when is come to the simplest of things also i feel slower than usual physical and mentally. Can you please tell me whats going on? I am 18 and went to college and just came. I have felt like this during the second semester, however not for the first. Can you please help.  <response>: Cannot say in your particular case without an examination. Frankly anything can do this. A minor infection sinus infection, tooth infection, etc. can do this. But practically any mental illness mild depression for example can also do this. Slowing, concentration problems are some symptoms of a depression likely to be very treatable. Loss of pleasure, feelings of depression or inadequacy, changes in sleep andor eating would establish a diagnosis of depression.
