Obesity has many psychiatric characteristics. One of these is its impact on cognitive functions. It is a known fact that obesity creates predisposition to Type II Diabetes which results from an insulin resistance.
Diabetes does not only affect the kidneys, nerves, blood vessels and eyes, but also the brain. An indication of this is the cognitive dysfunction often seen in Type II Diabetes.
In particular, it may give rise to disorders of the intellect, attention, psychomotor speed, visual perception. It’s most important impact is mental slow-down. It becomes more difficult for the person to memorize or learn.
EEG shows reduced alpha, beta and gamma rhythms in the temporo-occipital regions, and an increase in slow rhythms like delta and theta.
Of course the most important precaution is a public awareness and fight against the condition.
Psychiatric support is important in correcting cognitive dysfunctions related to diabetes. EEG plays a particular role in the follow-up process.
