What happens to the ventricles of a person with schizophrenia?
Objective: Enlargement of the lateral ventricles is among the most frequently reported macroscopic brain structural changes in schizophrenia, although variable in extent and localization. The authors investigated whether ventricular enlargement is related to regionally specific volume loss.
Why are ventricles enlarged in schizophrenia?
CONCLUSIONS: Thalamic shrinkage, especially of medial nuclei and the adjacent striatum and insular cortex, appear to be important contributors to ventricular enlargement in schizophrenia.
Do schizophrenics have larger brain ventricles?
Enlarged cerebral ventricles are found in 80% of individuals with schizophrenia, yet the mechanisms that lead to ventricular enlargement are mostly unknown.
What brain changes are most consistent in schizophrenia?
In MRI studies of schizophrenia, the most consistent findings include reduced gray matter volumes of the medial temporal, superior temporal, and prefrontal areas.
What do enlarged brain ventricles mean?
Hydrocephalus is the abnormal enlargement of the brain cavities (ventricles) caused by a build-up of cerebrospinal fluid (CSF). Hydrocephalus can be caused by problems with CSF secretion, CSF flow or CSF absorption.
Who is likely to get schizophrenia?
The risk for schizophrenia has been found to be somewhat higher in men than in women, with the incidence risk ratio being 1.3–1.4. Schizophrenia tends to develop later in women, but there do not appear to be any differences between men and women in the earliest symptoms and signs during the prodromal phase.
What kind of delusions do schizophrenics have?
Delusions are extremely common in schizophrenia, occurring in more than 90% of those who have the disorder. Often, these delusions involve illogical or bizarre ideas or fantasies, such as: Delusions of persecution – Belief that others, often a vague “they,” are out to get you.
