marijuana-020216.jpg Those who habitually use marijuana could experience declines in verbal memory later in life, according to a new study from researchers at the University of Queensland in Australia and Kings College, London. For the study the researchers collected data from the Coronary Artery Risk Development in Young Adults (CARDIA).

Scientists may be inching closer to a better understanding of what causes schizophrenia. The new study, from researchers at Harvard Medical School, Boston Children's Hospital and the Broad Institute, looked closely at a brain process called synaptic pruning. This process sheds redundant connections between neurons in the brain over the course of a lifetime.

A new wearable electric eye patch may help reduce some symptoms for PTSD suffers, according to researchers at the Semel Institute for Neuroscience and Human Behavior at UCLA's David Geffen School of Medicine in Los Angeles. The small electric patch sends jolts of electricity into the eye while a patient is sleeping and enables a treatment referred to as "trigeminal nerve stimulation" (TNS).

Sleepwoman-012916.jpg Overuse of social media could have a negative impact on sleep cycles, according to a new study from researchers at University of Pittsburgh School of Medicine. For the study the researchers collected data from 1,800 U.S. citizens between the ages of 19 and 32. They found that overall the respondents spent an average of 61 minutes a day on social media sites.

UrineSample-011816.jpg Urine odor may be able to detect early signs of Alzheimer's disease, according to a new study in mice. The study, published in the online journal Scientific Reports, involved mice, and later a machine, which were able to detect differences between the smell of urine from normal mice and that of three strains of mice that had been genetically altered to model aspects of Alzheimer's disease.

Jogging-011316.jpg Exercise may significantly reduce the risk of heart disease for those with depression, according to a new study from researchers at the Emory Clinical Cardiovascular Research Institute in Atlana. For the study the researchers examined health records for over 1,000 people who were previously not diagnosed with heart disease or depression.

Sleepwoman-011116.jpg Those who routinely suffer from a lack of sleep may be at an increased risk of Alzheimer's, according to a new study from researchers at the Oregon Health & Science University. For the study the researchers focused on the chemical processes that occur within the brain during sleep. They found that sleep cleans out various chemicals that are associated with the development of Alzheimer's.

People under the age of 45 who are suffering symptoms from a stroke may opt to ignore or delay trips to the hospital, according to a new study. Researchers at UCLA interviewed more than 1,000 people about their actions within the first three hours of experiencing common symptoms of stroke such as weakness, numbness, difficulty speaking, or difficulty seeing.

Those who suffer with type 2 diabetes may also be at an increased risk for dementia, according to a new study from researchers at Curtin University in Perth, Australia. For the study the researchers collected data from 14 studies including roughly two million patients, 100,000 of whom suffered from dementia.

Brain-123015.jpg The declaration of brain death may occur at different times depending on the hospital, according to a new study from researchers at the Yale Medical Center. For the study the researchers reviewed the brain death policies of 492 different hospitals between the years of 2012 and 2015. "It is encouraging that, even if some hospitals have not updated their policies . . ."
