Hi Mabel,
Welcome to the NeuroTalk Support Groups.

I'm not sure really where to direct you but you'll know more once he's seen the Neurologist, but in the meantime you could perhaps read some of the information in the Information threads on the
Peripheral Neuropathy Forum
to see if that fits the symptoms he's been experiencing.

There's a thread there in the Stickies called
Important Links to Useful Websites

We do have a Caregivers Support Forum

There are various forums related to mental health.
The best thing to do perhaps would be to look at the main list and then you can decide if you want to post there or not.
List of NeuroTalk Mental Health Conditions Forums

Hopefully you get some answers soon because not knowing can be the most difficult of times.

take care of yourself.
