This degenerative disease shares much in common with the better-known Alzheimer’s disease, but it takes hold much faster. Dementia develops as nerve cells die or deteriorate and a patient rarely survives more than seven years. The medical profession does not know why this happens and has no cure. The best they can do through medication is moderate some of the symptoms. LBD is tough to diagnose accurately while the patient is still living. To add to the confusion, it sometimes develops alongside Alzheimer’s disease and is very similar in its symptoms to Parkinson’s disease.

1. Hard to concentrate

A significant decline in the powers of concentration is a classic LBD symptom. It is far from unusual to notice that older adults find it harder to concentrate than they did in earlier years but this may be part of the normal aging process. If they suffer from LBD, expect to notice marked variations in their capabilities in this area. One day it seems as though their concentration is good and a short while later you find them unable to concentrate on tasks or subjects. If you can rule out any external factors that might affect their concentration levels at different times, an LBD diagnosis becomes a distinct possibility.
