Use software in mobile phone system to track changes in a client's
- tone of voice,
- regularity and speed of calling and texting,
- even vocabulary usage,
and thus recognise when their thought patterns are becoming abnormal, e.g. they may be entering a depressed ('flat'), anxious, angry, manic or psychotic phase.
Then use this information to
(a) alert the client, giving valuable self-awareness (e.g to take pre-emptive meds), and/or
(b) automatically alert (e.g. text) family or other carers, and/or
(c) trigger another device, worn by the client, to automatically administer treatment (words, music, meds, deep brain stimulation).
