I was reading the BBC and they had a discussion on dementia. This is a paragraph that alarmed me.
Conditions producing a dementia that can be reversed with treatment. These include hypothyroidism (under-active thyroid), vitamin B12 deficiency, folate deficiency, syphilis of the nervous system, subdural haematoma (a blood clot round the brain, usually following a blow to the head), hypercalcaemia (abnormally high calcium levels), undiagnosed diabetes, brain tumours or infections, and a condition called normal pressure hydrocephalus.
I have an underactive thyroid. It is being treated. So is my B12 deficiency and my folate deficiency. But I didn’t know these could cause dementia.
