Researchers Find Way to Increase Neuroplasticity and Treat “Negative” Symptoms of Schizophrenia

That is the title of the article I am writing about. This is and old article I have never written yet. I think it would be interesting if there were more like it. "Recent research at McLean Hospital and Harvard University Medical School shows a very promising possibility for the future treatment of the “negative” symptoms of schizophrenia by improving neuroplasticity––the ability of the nerve cell networks in the brain to physically adapt to changing conditions. Negative symptoms in schizophrenia include decrease in motivation, lack of attention, emotional flatness, memory loss and social withdrawal."  We really need something to help with negative symptoms. I write about them a lot in my blogs because I work and I know how hard it would be to do nothing because of negative symptom's.
The article goes on to say: "The research team was led by Joseph T. Coyle, M.D., a NARSAD Distinguished Investigator Grantee and Foundation Scientific Council Member. Dr. Coyle’s team at Harvard Medical School included Vadim Y. Bolshakov, Ph.D., a two-time NARSAD Grantee and Professor of Psychiatry. The researchers worked with mice to determine if they could find a cluster of abnormalities known to affect the brain’s hippocampus in people with schizophrenia. The mice were genetically engineered to have very low N-methyl-D-aspartate (NMDA) receptor activity in the brain, a condition suspected to be linked to impaired synaptic plasticity, memory formation and the negative symptoms of schizophrenia. The researchers investigated associated abnormalities including overall shrinkage of the hippocampus; decreased density of tiny nodules called dendritic spines, which serve as spots where synapses, or communications junctions, can form between neighboring neurons; and altered signaling pathways that help regulate neuroplasticity."  It would help people with mental illness that have negative symptoms. I know from the little I messed with neuroplasticity that it does help with memory.  The games anyway that is what I used.  It is seeing a picture and remembering where it was and hitting the right button. I performed better with time.
The article ends: "
In a paper published in the May 31st issue of Proceedings of the National Academy of Sciences, Drs. Coyle, Bolshakov and colleagues reported that the mice with low NMDA receptor activity “displayed impaired hippocampal plasticity, as well as the morphological [shape], neurochemical and cognitive abnormalities consistent with what is observed in schizophrenia.” This was an exciting finding, but then they went further. The mice used in the experiments had only about 10 percent of normal NMDA receptor activity because they had been engineered to lack D-serine, one of two molecules needed to activate the receptors. When the researchers treated the mice with D-serine, NMDA receptor function in the hippocampus was restored. Over time, all of the observed hippocampal symptoms proved reversible.
This new work lends important support to the theory that low activity (“hypoactivity”) in NMDA receptors in the brain can cause pathologies seen in people with schizophrenia and importantly, that the condition may be treatable and the symptoms reversed. While not the sole cause of schizophrenia, the ability to reverse this hypoactive condition in mice suggests it may be possible to develop D-serine-based treatments for use in people―what could prove to be a breakthrough in the treatment of schizophrenia."  So why has this treatment came available by now. I know it takes time although there has been nothing new to happen to help people with mental illness in a long time.
