3. Increased fatigue
Often, patients who have early on-set dementia feel as if they are more tired than usual and appear to be almost lethargic in nature. For example, a person with dementia may not have the energy to complete everyday tasks or may lose interest in doing things that he or she once loved.
Likewise, the individual may become very physically tasked after completing a simple activity, such as taking a shower or going grocery shopping.
Again, this is because of the impact this disease has on the neurons in the brain, which can impact interest and energy levels.
