Causes of Memory Loss

MCI and Dementia

The brain is the command-and-control center of your life. It uses its over 100 billion neurons to perceive and analyze incoming information; decide what, if anything, to do about the information; and then instruct the body to do it.

The brain is divided into lobes and regions. Each brain lobe is responsible for specific functions, such that impairment in that lobe results in specific problems.

Lobe	Functions	Problems
Medial Temporal Lobe	Short-term memory Learning	Short-term memory loss
Lateral Temporal Lobe	Hearing/Listening Reading Reading social cues Recognizing objects by sight Anger control Naming things	Reading problems Word-finding problems Trouble reading social cues Episodic rage Poor object recognition Religious or moral preoccupation
