With amino acid diet, mice improve after brain injury
Neurology researchers have shown that feeding amino acids to brain-injured mice restores their cognitive abilities and may set the stage for the first effective treatment for cognitive impairments suffered by people with traumatic brain injuries. If these animal results can be translated to human medicine, there would be a broad clinical benefit. Every 23 seconds, a man, woman or child in the US

An Animal Model For Schizophrenia Identifies A Novel Approach For Treating Cognitive Impairments Associated With Schizophrenia
Researchers have been seeking a safe and effective way to treat cognitive impairments associated with schizophrenia by enhancing N-methyl-D-aspartate (NMDA) glutamate receptors. Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder. The first generation of studies trying to stimulate NMDA receptors administered large amounts of substances, like glyc
