ADHD medication may affect brain development in children

A drug used to treat attention-deficit/hyperactivity disorder (ADHD) appears to affect the development of the brain's signal-carrying white matter in children with the disorder, according to a study published in the journal ...

Our brains do change from early to mid-adulthood

Scientists in China have found that significant microstructural changes occur in the brain from early to mid-adulthood, allowing them to accurately estimate an individual's age from their brain structure. The findings are ...

Glaucoma may result from white matter degeneration

(HealthDay)—Glaucoma may be associated with lower fractional anisotropy in the optic radiations, forceps major, and corpus callosum, possibly as a result of white matter degeneration, according to a study published online ...

Schizophrenia: A disorder of neurodevelopment and accelerated aging?

Many lines of evidence indicate that schizophrenia is a disorder of neurodevelopment. For example, genes implicated in the heritable risk for schizophrenia are also implicated in the development of nerve cells and their connections. ...

White matter microstructural integrity altered in T1DM

(HealthDay)—Youth with type 1 diabetes mellitus (T1DM) exhibit a pattern of regional diffusion tensor imaging differences that is suggestive of axonal injury or degeneration and may be related to episodes of severe hypoglycemia, ...

Anisotropy

Anisotropy (/ˌænaɪˈsɒtrəpi/) is the property of being directionally dependent, as opposed to isotropy, which implies identical properties in all directions. It can be defined as a difference, when measured along different axes, in a material's physical or mechanical properties (absorbance, refractive index, conductivity, tensile strength, etc.) An example of anisotropy is the light coming through a polarizer. An example of an anisotropic material is wood, which is easier to split along its grain than against it.
