Even if a complete neuron doesn't die, if a huge chunk of the synapses are destroyed, whatever that neuron was doing before, it's doing a fraction afterwards: a measurable, consistent, and symptom-correlated loss of dopamine nerve terminals averaging 18 percent across the long COVID group. with localized damage to areas that match Long COVID symptoms: “In other illnesses this magnitude of loss is associated with symptoms: loss in one region is associated with trouble with motivational energy problems, loss in another region is associated with some slowness of movement, and loss in a third region is associated with memory trouble.” in short, the terminals are gone, the loss is measurable, and it correlates with the symptoms patients have been reporting for years. https://tech-paper.com/scientists-finally-have-a-biological-explanation-for-why-long-covid-patients-lose-motivation-and-cant-think-clearly-they-scanned-their-brains-and-found-the-dopamine-system-was-physically-damaged/ #neuroscience #neurology #science #LongCOVID #PASC #health

Millions of people with long COVID report the same cluster of symptoms: a crushing lack of motivation, an inability to think clearly, memory that slips, movements that feel slower than they should. For years, these complaints sat in an uncomfortable medical grey zone. The symptoms were real, the patients were suffering, but the biological explanation remained frustratingly out of reach.A team at the University of Toronto just published what may be the clearest physical evidence yet for what is a

How workplace stress hijacks the nervous system to cause headaches − and a neurologist’s guide to managing them

A high-pressure work environment can exacerbate headaches, but taking steps to manage stress throughout the day can help.

Jesse Jackson’s misdiagnosis of Parkinson’s is common – new genetic discovery could lead to treatment for this deadly disease - Like Rev. Jackson, they misdiagnosed me and it took them a long time to DX my Multiple System Atrophy. RIP Rev. Jackson. The "Parkinson's" part of these illnesses are just foreplay for the disease that is to come. are characterized by the primary features of Parkinson disease, including bradykinesia, ataxia, resting tremor, and rigidity but also include additional features, depending on which subset. I will be glad when they break Parkinson-plus syndromes away from Parkinson's completely. Many doctors don't even know what they are and they are becoming more common. COVID research is leading to new discoveries and treatment of PPS. One area seeing strides is POTS. There was no money for POTS in medical research until COVID made it a standard ailment of Long COVID. Parkinson-plus syndromes include multiple system atrophy (MSA) (formerly known as Shy–Drager syndrome), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD), Dementia with Lewy bodies (DLB), Pick's disease and olivopontocerebellar atrophy. #Parkinsons #MSA #Neurology #MedMastodonhttps://theconversation.com/jesse-jacksons-misdiagnosis-of-parkinsons-is-common-new-genetic-discovery-could-lead-to-treatment-for-this-deadly-disease-276944 https://en.wikipedia.org/wiki/Parkinson-plus_syndrome https://www.ncbi.nlm.nih.gov/books/NBK585113/

People typically die from progressive supranuclear palsy within 7 to 10 years. There is currently no specialized treatment or effective screening for this neurodegenerative disease.

AI models are getting better at studying and diagnosing specific diseases and neuropsychiatric conditions. Case in point, AI has shown promise in uncovering patterns associated with tumors, strokes and neurodegenerative diseases by analyzing large amounts of brain scans collected using magnetic resonance imaging.

The last words that legendary Apple founder Steve Jobs uttered were “Oh, wow, oh wow, oh wow.” It’s anyone’s guess what spurred Jobs’ comments. But scientists may be closing in on what happens in the final moments of life by gathering data on brain activity from patients who are dying.
