Common class of drugs linked to increased risk of Alzheimer’s disease

A team of scientists, led by researchers at University of California San Diego School of Medicine, report that a class of drugs used for a broad array of conditions, from allergies and colds to hypertension and urinary incontinence, may be associated with an increased risk of cognitive decline, particularly in older adults at greater risk for Alzheimer’s disease (AD).

Alzheimer: cientistas diminuem inflamação no cérebro e revertem demência

Cientistas dizem que, pela primeira vez, conseguiram reverter a demência em ratos reduzindo a inflamação no cérebro, em vez de atacar as proteínas invasoras típicas que provocam o problema, as chamadas as placas amilóides encontradas em pessoas com doença de Alzheimer.

O último estudo publicado na Science Translational Medicine sugere que o direcionamento da inflamação no cérebro pode deter a demência.

Watching pornography can catapult the brain into a catastrophic state

Science is only just beginning to reveal the neurological repercussions of porn consumption.

Pornography has existed throughout recorded history, transforming with the introduction of each new medium. Hundreds of sexually explicit frescoes and sculptures were found in the Mount Vesuvius ruins of Pompeii.

Since the advent of the internet, porn use has skyrocketed to dizzying heights. Pornhub, the world’s largest free porn site, received over 33.5 billion site visits during 2018 alone.

Science is only just beginning to reveal the neurological repercussions of porn consumption. But it is already clear that the mental health and sex lives of its widespread audience are suffering catastrophic effects. From depression to erectile dysfunction, porn appears to be hijacking our neural wiring with dire consequences.

Drogas que agem sobre inflamação no cérebro podem reverter demência

Com o envelhecimento, estrutura que protege o sistema nervoso central, bloqueando substâncias tóxicas, perde eficiência

O declínio cognitivo que ameaça o envelhecimento poderá ser detido, ou pelo menos retardado, através de drogas que eliminariam processos inflamatórios no cérebro. A incrível novidade foi publicada ontem na revista médica “Science Translational Medicine”, criada pela Associação Americana para o Avanço da Ciência. Trata-se de um trabalho conjunto dos pesquisadores Daniela Kaufer, da Universidade de Berkeley, Califórnia, e Alon Friedman, das universidades Ben-Gurion do Negev (Israel) e Dalhousie (Canadá). Embora ainda restrito a experiências feitas com camundongos, tem grande potencial de aplicação em humanos.

Os cérebros de ratinhos senis que receberam a droga passaram a se assemelhar aos de cobaias mais jovens o que, segundo a cientista, é promissor. “Nossa tendência é pensar o cérebro mais velho da mesma forma como encaramos a degeneração neurológica: como se a idade avançada envolvesse a perda de funções e a morte das células. No entanto, essa descoberta nos conta uma nova história sobre por que o cérebro não está funcionando bem: é por causa de uma carga inflamatória que pode ser combatida”, afirmou a doutora Kaufer.

Hyperbaric oxygen therapy for Alzheimer’s disease

 

 

 

 

 

 

Dr. Paul Harch, Clinical Professor and Director of Hyperbaric Medicine at LSU Health New Orleans School of Medicine, and Dr. Edward Fogarty, Chairman of Radiology at the University of North Dakota School of Medicine, report the first PET scan-documented case of improvement in brain metabolism in Alzheimer’s disease in a patient treated with hyperbaric oxygen therapy (HBOT).

Feeling Hazy? Here’s Your Definitive Guide To Brain Fog

 

 

 

 

 

 

“Brain fog” is a term commonly used by patients when they are trying to describe a lack of mental clarity, mild confusion, loss of focus and attention, poor concentration, or even just a generalized sense of not feeling their best. As an integrative neurologist, my first job is to make sure that nothing serious is going on, which means conducting a brain MRI, an electroencephalogram, blood tests, and even cerebrospinal fluid studies. But, very often with brain fog, all of these conventional tests will come back without abnormalities, and yet, the patients will have these uncomfortable symptoms. What’s the catch?
