Analyzing and Comparing the Brain Activity of Alzheimer's Patients with
Healthy Subjects
Abstract
Alzheimer’s Disease has been a long standing mental disorder that we
have gained a lot of knowledge about. However, no matter how much we
have learned, we still are yet to discover a magnitude more about the
disease. Alzheimer’s disease is a progressive neurological disorder
characterized by cognitive decline, memory loss, and behavioral changes.
It is the most common cause of dementia, impacting a person’s ability to
perform daily tasks and ultimately affecting their quality of life. We
can study this using brainwaves. The 5 types of brainwaves each
correlate to a different type of mental activity, which gives more
information on various diseases like Alzheimer’s. Through this paper, we
hope to find common trends on the brainwaves of an Alzheimer’s patient
compared to a control subject with no mental disorders. All patterns
will be tried to conclude to the reason behind that data. The Muse 2
Headband was used to collect the recordings of brainwave data in this
study. Recordings of two subjects (one of which is the control) in two
different conditions (active and resting) will be tested. The EEG data
will then be compiled by MATLAB and put on a Spectral Plot to analyze
the Electrical Brain Responses. The results show that readings in all
brain waves other than Beta and Gamma were inactive and similar between
both subjects. Beta and Gamma wave analysis proves that the Alzheimer’s
Disease subject had lower activations in their brain due to a higher log
of frequency power in those waves.
