Given only the symptoms that you have described, it is difficult to determine which disorder your mother may have. You mentioned that when she talks, her hands move according to what she is saying. This symptom is not a characteristic of any particular mental health disorder. I would need much more specific information regarding exactly what you mean when you describe her hands moving according to what she is saying. You also mentioned that she doesn’t shower. Again, this is a concerning symptom but it is not characteristic of any specific mental health disorder per se. Individuals who are depressed may not shower because they have a low level of energy but your overall description of your mother does not necessarily indicate depression. An individual may not shower if they are in the early phases of a psychotic episode but nothing you have written necessarily indicates that she is psychotic. You also wrote that she acts ‘normal’ in the presence of psychiatric professionals. What exactly do you mean by normal? Is she pretending or lying? Generally individuals who are experiencing genuine psychiatric symptoms can’t simply “turn it off.” It would also be interesting to know whether she showers before one of her scheduled psychiatric examinations.
This is a difficult issue because you cannot force anyone to seek help if they do not want it. Generally, the only way an individual can be forced into treatment is if they are displaying behaviors that are life-threatening. If you notice that your mother is not eating, along with not showering and displaying other disturbing symptoms you should call a local crisis team who can come in to your home and evaluate her condition. If she is unable to care for herself, then she may be admitted to the hospital even if against her will.
I would encourage you to contact local physicians or mental health professionals to ask their opinion of her symptoms. I do not believe that viewing the video is the best way to determine her diagnosis. A face-to-face interview with psychiatric professionals is the best way to proceed. You should continue to encourage your mother to be evaluated by medical and psychiatric professionals. The concern is that her odd behavior may possibly be an early sign of an untreated medical condition. Even if she continues to act “normal” in an evaluation setting, a good therapist should be able to pick up other symptoms. Also, at a doctor’s appointment you should report your concerns even if your mother is present in the room. She may become upset with you but it’s okay because it is necessary for her medical and psychiatric safety. I hope that she is able to get the help she needs. Please take care. I wish you well.
