Vitamin B12 deficiency symptoms, like those of many other treatable health conditions, can be virtually identical to Alzheimer’s disease and other related dementias. As many as 20% of people over age 65 have low Vitamin B12 levels. Correcting the deficiency can help them resume a full and normal lives.
Vitamin B12 deficiency symptoms include:
- Loss of appetite, stomach upset, weight loss
- Diarrhea or constipation
- Numbness and tingling of hands and feet
- Pale skin
- Shortness of breath
- Rapid heartbeat
- Weakness, fatigue, light-headedness
- Sore mouth and tongue
- Easy bruising or bleeding, including bleeding gums
- Depression
- Confusion or change in mental status in severe or advanced cases. This is sometimes confused with dementia. More importantly, even a moderate deficiency of this important vitamin and its counterpart, folic acid, may ultimate contribute to the onset of Alzheimer’s disease or other related dementias.
