What part of the brain is affected in schizophrenia?
Schizophrenia is associated with changes in the structure and functioning of a number of key brain systems, including prefrontal and medial temporal lobe regions involved in working memory and declarative memory, respectively.
What is right hemisphere dysfunction?
Right hemisphere damage (RHD; also known as “right hemisphere disorder” and “right hemisphere brain damage”) is an acquired brain injury—usually secondary to stroke or TBI—that causes impairments in language and other cognitive domains that affect communication.
What in the brain causes schizophrenia?
Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Some studies indicate an imbalance between the 2 may be the basis of the problem. Others have found a change in the body’s sensitivity to the neurotransmitters is part of the cause of schizophrenia.
What does the right hemisphere deal with?

What is wrong with the brain of a schizophrenic?
Individuals with schizophrenia have up to 25% less volume of gray matter in their brains, especially in the temporal and frontal lobes (known to be important for coordination of thinking and judgment). Patients demonstrating the worst brain tissue losses also tend to show the worst symptoms.
What is hemispheric dysfunction?
Right hemisphere dysfunction (RHD) arises from lesions to the right hemisphere. For people with a dominant left hemisphere, the form and content of language appear normal until deep testing is performed. People with RHD have a high likelihood of demonstrating left hemispatial neglect, including left visual neglect.
What is the meaning of right hemisphere?

What does it mean if your right brain is dominant?

What happens when the right hemisphere is damaged?
With right hemisphere brain damage (known as RHBD or RHD), a person may have trouble with things like attention, perception, and memory, as well as loss of mobility and control on the left side of the body, since each hemisphere controls functions on the opposite side of the body.
What is the meaning of right hemisphere damage?
Right hemisphere damage (RHD; also known as “right hemisphere disorder” and “right hemisphere brain damage”) is an acquired brain injury—usually secondary to stroke or TBI—that causes impairments in language and other cognitive domains that affect communication.
What is the function of the right hemisphere in communication?
Overview. The right hemisphere of the brain participates in many communication skills, primarily at the semantic (word and discourse) and pragmatic levels. Right hemisphere damage (RHD; also known as “right hemisphere disorder” and “right hemisphere brain damage”) is an acquired brain injury—usually secondary to stroke or TBI—that causes…
What is the prevalence of schizophrenia?
Schizophrenia is a chronic and severe mental disorder with a typical onset in adolescence and early adulthood and a lifetime prevalence of about 1%. On average, males have their illness onset 3 to 4 years earlier than females.
What is the age of onset of schizophrenia?
Onset of schizophrenia is very rare before age 11, and prior to age 18 the illness has been called “early-onset schizophrenia” (EOS), while onset before age 13 has been termed “very early-onset schizophrenia” (VEOS; Werry, 1981 ).
