Hello and welcome to HCM,
The symptoms of memory loss
, tiredness, numbness, feeling cold, defects in vision, sleep disturbance suggest a neuronal or vascular problem.
Multiple sclerosis is one of the conditions which causes demyelination
of the nerves.
The symptoms depend on the organs involved.
A CSF examination is required to look for pleocytosis.
Pleocytosis is presence of mononuclear cells in CSF.
MRI of brain and spinal cord
is also required.
Vascular lesion has also to be looked for.
You need to consult a neurologist
for clinical examination, investigations and thus management.
thanks and take care
Dr Shailja P Wahal
