Anosognosia and prosopagnosia

Anosognosiaand prosopagnosia

Theright hemisphere of the brain is tasked with coordinating the leftside of the body. Additionally, it is involved in tasks that requirecreativity. Other functions include art awareness, insight, andimagination and 3-D forms. Damages to the right hemisphere will thuscause disruptions in above-stated functions. Some of the syndromesassociated with the right hemisphere include Anosognosia andprosopagnosia.

Anosognosiaresults in impaired awareness. Those who suffer from someneurological conditions such as Alzheimer’s disease seems to beunaware of their condition (Gasquoine, 2016). Even after beingdiagnosed with the, most patients usually insist that there isnothing wrong with them. The hypothesized site of damage, in thiscase, is the frontotemporal-parietal area. The explanation for thisbehavior is that the disease affects the right hemisphere whose roleinvolves insight and the concept of self-awareness.

Prosopagnosia,on the other hand, refers to one’s inability to recognize familiarfaces. Individuals suffering from this condition often develop socialanxiety which is often characterized by embarrassment (Gasquoine,2016). The hypothesized site of damage here is the occipitotemporal`slobe. It has been associated with other conditions such as the lefthemianopsia that result in loss of vision.

Someof the similarities between these conditions are that they causepersonality problems, and both result in neurological damages. Forinstance, in Anosognosia, an individual loses insight while inProsopagnosia one has clue of those around him or here. Lastly, bothhave been associated with mental conditions such as autism andschizophrenia. The main difference between the two is that some formsof Prosopagnosia can be acquired unlike Anosognosia. While it may beeasier to recognize Anosognosia, diagnosing Prosopagnosia is quite achallenge because some people usually ignore the syndromes.
