(Medical Xpress)—Scientists at Washington University School of Medicine in St. Louis have helped identify many of the biomarkers for Alzheimer's disease that could potentially predict which patients will develop the disorder later in life. Now, studying spinal fluid samples and health data from 201 research participants at the Charles F. and Joanne Knight Alzheimer's Disease Research Center, the researchers have shown the markers are accurate predictors of Alzheimer's years before symptoms develop. http://medicalxpress.com/news/2013-05-alzheimer-markers-mental-decline.html Alzheimer's disease & dementia Tue, 14 May 2013 06:48:36 EST news287732906 (Medical Xpress)—Scientists' picture of how a gene strongly linked to Alzheimer's disease harms the brain may have to be revised, researchers at Washington University School of Medicine in St. Louis have found. http://medicalxpress.com/news/2013-05-perspective-role-major-alzheimer-gene.html Medical research Tue, 07 May 2013 07:32:39 EST news287130751 The virus that causes cold sores, along with other viral or bacterial infections, may be associated with cognitive problems, according to a new study published in the March 26, 2013, print issue of Neurology. http://medicalxpress.com/news/2013-03-cold-sore-memory-problems.html Neuroscience Mon, 25 Mar 2013 16:00:01 EST news283435534 Cognitive problems with memory and behavior experienced by individuals with schizophrenia are linked with changes in brain activity; however, it is difficult to test whether these changes are the underlying cause or consequence of these symptoms. By altering the brain activity in mice to mimic the decrease in activity seen in patients with schizophrenia, researchers reporting in the Cell Press journal Neuron on March 20 reveal that these changes in regional brain activity cause similar cognitive problems in otherwise normal mice. This direct demonstration of the link between changes in brain activity and the behaviors associated with schizophrenia could alter how the disease is treated. http://medicalxpress.com/news/2013-03-brain-responsible-cognitive-symptoms-schizophrenia.html Neuroscience Wed, 20 Mar 2013 12:00:01 EST news282999473 Sleep is disrupted in people who likely have early Alzheimer's disease but do not yet have the memory loss or other cognitive problems characteristic of full-blown disease, researchers at Washington University School of Medicine in St. Louis report March 11 in JAMA Neurology. http://medicalxpress.com/news/2013-03-loss-alzheimer-symptoms.html Alzheimer's disease & dementia Mon, 11 Mar 2013 16:00:03 EST news282221783 People with multiple sclerosis (MS) who have cognitive problems, or problems with memory, attention, and concentration, have more damage to areas of the brain involved in cognitive processes than people with MS who do not have cognitive problems, according to a study published in the March 6, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology. http://medicalxpress.com/news/2013-03-people-ms-related-memory-attention-problems.html Neuroscience Wed, 06 Mar 2013 16:01:37 EST news281808088 (Medical Xpress)—Data from the largest multicenter study accessing cognitive functioning in children with multiple sclerosis (MS) reveals that one-third of these patients have cognitive impairment, according to a research paper published in the Journal of Child Neurology. Led by Lauren B. Krupp, MD, Director of the Lourie Center for Pediatric Multiple Sclerosis at Stony Brook Long Island Children's Hospital, the study indicates that patients experience a range of problems related to cognition. http://medicalxpress.com/news/2013-02-children-ms-cognitive-impairment.html Neuroscience Wed, 06 Feb 2013 08:40:01 EST news279361828 People who study or treat Alzheimer's disease and its earliest clinical stage, mild cognitive impairment (MCI), have focused attention on the obvious short-term memory problems. But a new study suggests that people on the road to Alzheimer's may actually have problems early on in processing semantic or knowledge-based information, which could have much broader implications for how patients function in their lives. http://medicalxpress.com/news/2012-12-early-cognitive-problems-eventually-alzheimer.html Alzheimer's disease & dementia Fri, 28 Dec 2012 11:06:02 EST news275915154 The hallmark of Parkinson's Disease is the uncertain gait and movement caused by the destructions of neurons producing the neurotransmitter dopamine. http://medicalxpress.com/news/2012-11-explanation-cognitive-problems-parkinson-patients.html Parkinson's & Movement disorders Wed, 28 Nov 2012 09:00:05 EST news273315593 MRI shows changes in the brains of people with post-concussion syndrome (PCS), according to a new study published online in the journal Radiology.

Heavy alcohol consumption is another well-known unhealthy habit of this age group. A new study from the University of Missouri shows that when college students combine these two unhealthy habits, their long-term health may be affected.
