Here s how one psychedelic experience may lessen trauma of racial injustice ANI | Updated: Jan 02, 2021 14:07 IST
Washington [US], January 2 (ANI): A single positive experience on a psychedelic drug may help reduce stress, depression and anxiety symptoms in Black, Indigenous and people of colour whose encounters with racism have had lasting harm, according to findings of a new study.
The participants in the retrospective study reported that their trauma-related symptoms linked to racist acts were lowered in the 30 days after an experience with either psilocybin (Magic Mushrooms), LSD or MDMA (Ecstasy). Their experience with psychedelic drugs was so powerful that they could recall and report on changes in symptoms from racial trauma that they had experienced in their lives, and they remembered it having a significant reduction in their mental health problems afterwards, said Alan Davis, co-lead author of the study and an assistant professor
Study sheds light on explanation for lack of blood oxygenation detected in many COVID-19 patients ANI | Updated: Dec 30, 2020 07:53 IST
Washington [US], December 30 (ANI): One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as silent hypoxemia or happy hypoxia . A recent study sheds light on the explanation for the lack of blood oxygenationdetected in many COVID-19 patients.
The study was published in the journal function.
Patients suffering this phenomenon, the causes of which are still unknown, have severe pneumonia with markedly decreased arterial blood oxygen levels (known as hypoxemia). However, they do not report dyspnea (subjective feeling of shortness of breath) or increased breathing rates, which are usually characteristic symptoms of people with hypoxemia from pneumonia or any other cause.
Brain imaging predicts PTSD after injury, finds study ANI | Updated: Dec 30, 2020 08:23 IST
Philadelphia [US], December 30 (ANI): Posttraumatic stress disorder (PTSD) is a complex psychiatric disorder brought on by physical and/or psychological trauma. How its symptoms, including anxiety, depression and cognitive disturbances arise remains incompletely understood and unpredictable. Now, researchers using magnetic resonance imaging (MRI) have found potential brain biomarkers of PTSD in people with traumatic brain injury (TBI).
The study appears in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, published by Elsevier. The relationship between TBI and PTSD has garnered increased attention in recent years as studies have shown a considerable overlap in risk factors and symptoms, said lead author Murray Stein, MD, MPH, FRCPC, a Distinguished Professor of Psychiatry and Family Medicine & Public Health at the University of Califor
Gut cells sound the alarm when parasites invade, says study ANI | Updated: Dec 29, 2020 07:38 IST
Washington [US], December 29 (ANI): A chain reaction led by cells lining the intestines tips the immune system off to the presence of the parasite Cryptosporidium, according to a study led by researchers in the School of Veterinary Medicine. To effectively combat an infection, the body first has to sense it s been invaded, then the affected tissue must send out signals to corral resources to fight the intruder. Knowing more about these early stages of pathogen recognition and response may provide scientists with crucial clues when it comes to preventing infections or treating inflammatory diseases resulting from overactive immunity.
Common brain malformation traced to its genetic roots: Study ANI | Updated: Dec 29, 2020 07:38 IST
Washington [US], December 29 (ANI): In new research, scientists at Washington University School of Medicine in St. Louis have shown that Chiari 1 malformation (common brain disorder) can be caused by variations in two genes involved in brain development.
About one in 100 children has a common brain disorder called Chiari 1 malformation, but most of the time such children grow up normally and no one suspects a problem. But in about one in 10 of those children, the condition causes headaches, neck pain, hearing, vision and balance disturbances, or other neurological symptoms.
