Biological components are less reliable than electrical ones, and rather than instantaneously receive the incoming signals, the signals arrive with a variety of delays.
خرف أجسام ليوي هو مرض تنكسي عصبي متفاقم يشترك في بعض سماته مع داء باركينسون و داء الزهايمر، ولكنه قد يكون أكثر صعوبة في التشخيص. يمكن أن تشمل الأعراض الهلوسات واضطرابات الحركة ومشاكل في الإدراك واضطرابات النوم والاكتئاب.
A demência por corpos de Lewy (DCL) é uma doença neurodegenerativa progressiva que compartilha características tanto da doença de Parkinson quanto da doença de Alzheimer, mas que pode ser mais difícil de ser diagnosticada. Os sintomas podem incluir alucinações, distúrbios do movimento, problemas cognitivos, problemas de sono e depressão.
La demencia con cuerpos de Lewy (DCL) es una enfermedad neurodegenerativa progresiva que comparte características tanto de la enfermedad de Parkinson cuanto de la enfermedad de Alzheimer, pero que puede ser más difícil de diagnosticar. Los síntomas pueden incluir alucinaciones, trastornos del movimiento, problemas cognitivos, problemas para dormir y depresión.
Los seminarios web cooperativos se lanzaron en junio de 2021 en dos idiomas: francés e inglés. Los beneficios de la empresa cooperativa se extendieron mucho más allá de lo que esperaban los organizadores.
The effects of rapid exposure to alcohol in early pregnancy – when a woman consumes as many as six drinks in an hour – can be detected in the placenta, an UdeM study on mice suggests.
Researchers from UC San Francisco have developed a machine learning algorithm to enhance 3T MRIs by synthesizing 7T-like images that approximate real 7T MRIs. Their model enhanced pathological tissue with more fidelity for clinical insights and represents a new step toward evaluating clinical applications of synthetic 7T MRI models.
Scientists have linked neuropsychiatric disorders, such as schizophrenia and autism, to changes in many genes involved in early brain development. However, more research is needed to understand how these gene variants influence the biological mechanisms that underlie these disorders.
A new study has found some cancers to be slightly more frequent in people with multiple sclerosis (MS) than in people without MS. The study is published in the October 9, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. Types of cancers found to have a small increased risk include bladder, brain and cervical cancers. The study does not prove that MS increases a person’s risk of cancer. It only shows an association.
Researchers have identified how the architecture of brain circuits helps different species flexibly adapt to new mating signals across evolutionary timeframes.
A person’s IQ during high school is predictive of alcohol consumption later in life, according to a study by UT Southwestern Medical Center researchers published in Alcohol and Alcoholism. Participants with higher IQ levels were significantly more likely to be moderate or heavy drinkers, as opposed to abstaining.
A simple scoring system from Rutgers Health experts and others predicts outcomes of minimally invasive procedures, potentially expanding treatment options.
A UCLA-led study has created a map of DNA modification in two regions of the brain critical to learning, memory and emotional regulation. The map offers a benchmark for ensuring stem cell-based models accurately replicate human brain development.
Three researchers from Washington University in St. Louis have received highly competitive and prestigious NIH Director’s awards, totaling $10 million in “High Risk, High Reward” medical research funding to be used over the next five years.
A multi-institutional program led by researchers at the Center for Data Driven Discovery in Biomedicine (D3B) at Children’s Hospital of Philadelphia (CHOP) has received up to $10 million Advanced Research Projects Agency for Health (APRA-H) Mission Office Innovative Solutions Openings award to research, validate and implement a new model for sharing and integrating data at a national level.
Improving clinical outcomes in stroke patients by closing a gap between successful re-opening of a blocked vessel through endovascular surgery and a reduction of disability is the focus of a $2.5 million grant awarded to UTHealth Houston researchers.
In a pioneering longitudinal study, researchers tracked one person’s brain and behavioural activity for five months using brain scans and data from wearable devices and smartphones. They found that the everyday effects of sleep, exercise, heart rate and mood — both good and bad — could linger in our brains for over two weeks.
