Keeping mentally active by reading books or writing letters helps protect the brain in old age, a study suggests.

The rate and extent of damage to the spinal cord and brain following spinal cord injury have long been a mystery. Now new research has found evidence that patients already have irreversible tissue loss in the spinal cord within 40 days of injury. The study, published in the journal Lancet Neurology, used a new imaging measurement technique, developed at the Wellcome Trust Centre for Neuroimaging (UCL). This enables the impact of therapeutic treatments and rehabilitative interventions to be determined more quickly and directly.

UCSF neuroscientists have found that by training on attention tests, people young and old can improve brain performance and multitasking skills.

Researchers are striving to understand the different genetic structures that underlie at least a subset of autism spectrum disorders. In cases where the genetic code is in error, did that happen anew in the patient, perhaps through mutation or copying error, or was it inherited? A new study in the American Journal of Human Genetics finds evidence that there may often be a recessive, inherited genetic contribution in autism with significant intellectual disability.

A specific brain disruption is present both in individuals diagnosed with schizophrenia and those with bipolar disorder, adding to evidence that many mental illnesses have biological similarities.
