INTRODUCTION
 Overview of the intricate structure of the
human brain, (Lewis, 2016).
 The origin of Alzheimer's disease resonates
from the genetic, environmental and lifestyle
factors.
 It is associated with decline in cognitive
decline in memory loss, (MacGill, 2016).
 Alzheimer’s disease is a type of dementia that
develops from the disruptions in the
neurological functions of the human brain.
 The disease has effects on the biological,
neurological and memory problems.

THE HUMAN BRAIN
 Command and control centre of the human
nervous centre.
 The brain has three distinct parts namely
forebrain, midbrain and hind brain.
 The cerebrum consists of two hemispheres and
the brainstem lies underneath it. Behind the
brainstem is the cerebellum.
 The brainstem, consisting of the medulla
oblongata, pons, and midbrain, relays
information between the brain and the body.

BRAIN LIMBIC SYSTEM
 Is formed from the cortical and subcortical
structures like the amygdala, hipocampus,
mammillary bodies, fornix, cingulate gyrus, and
the parahippocampal gyrus which engage
intrinsically.
 Amygdala receives multiple sensory information
which mediates emotional parts of memory and
fear
 Cerebelluma has vital role in carrying out non
thinking functions.
