Brain differences in mental illness

Diseases that directly affect the brain can produce changes of all kinds: cognitive, emotional, behavioral ... Sometimes the changes can even be seen with the naked eye when differentiating them between a normal brain and a diseased brain. This happens for example with Alzheimer's.

In this first image you can see the brains below that have a different appearance, for example they have a smaller size, since the brains of Alzheimer's patients weigh less, they also have more holes in the brain (brain furrows), more widely spaced and the posterior region, which is in charge of the trial, is more reduced.

The following image also shows the reduced size and wider furrows of the brain with Alzheimer's. You can also see the difference between the healthy brain and the diseased brain in the memory and language areas, which are quite affected by Alzheimer's disease..

In the last image you can see the differences from another point of view:

Another of the most studied brains apart from that of people with Alzheimer's is that of people with schizophrenia.

Although there are cases of schizophrenia with normal brains, the schizophrenic brain generally looks different to the naked eye showing significant dimorphism.

The schizophrenic brain usually has a lower brain weight, a lower depth of the fissures and a ventricular widening.

In the image these characteristics can be seen more clearly. Two brains of two identical 28-year-old twins are shown, the right one being the one suffering from schizophrenia. You can see that it contains many more dark parts inside the brain (ventricles) and the "gaps" (fissures) that are much more open and separated.
