Computed tomography of the brain in patients with acute psychosis and in healthy volunteers

Acta Psychiatrica Scandinavica

Evidence has been obtained by computed tomography (CT) that some chronic schizophrenic patients have enlarged cerebral ventricles and other brain abnormalities when compared to other patient groups and to healthy controls (Johnstone et al. (1976), Weinberger et al. (1979)). In order to investigate whether structural brain abnormalities can be demonstrated also in younger patients with acute psychosis we have undertaken a CT study in 46 patients and 46 healthy volunteers. Twenty-eight of the patients fulfilled the Research Diagnostic Criteria for schizophrenia. Nineteen had not been hospitalized for psychiatric reasons before. The lateral and third ventricles were significantly wider in the patients than in the volunteers. In the volunteers there was a significant positive correlation between age and size of the lateral ventricles, whereas in the patients, particularly those fulfilling the criteria for schizophrenia, no such correlation was obtained. These results indicate that schizophrenia may be associated with patho-physiological processes which interfere with the normal age-related enlargement of the ventricles. Signs of cortical atrophy, CSF circulation disturbances and reversed asymmetry of the occipital lobes were more f...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
