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

Non-Financal Mutual Aid Request, seeking information Hover or focus to reveal Sensitive
We are a plural collective with a form of mast cell disorder. We know this due to antihistimine medication and diet being enough to seriously reduce our symptoms, however we have yet to fully adress and stabilize them. One of those symptoms is a form that no individual we've met or heard of, so far, has any direct knowledge of. We are seeking information on it, both so we can better adress it, and so we can better discuss it with others and ourselves. When we are having a histamine reaction, or histamines are too built up in our body. Some combination of our symptoms results in heightened fear, as we understand is typical for epinephrine reactions. For us, uniquely. This also comes with extremely heightened paranoia, sensitivity, and defensiveness. Which is what we cannot fully understand. Even if we know it might be coming, and even if we prepare for it ahead of time, we are not sure what if anything we can do to prevent us from causing harm as result of this. (Beyond extreme over-compensation like 24/7 psychiatric drugs, even when not having a reaction) This state of mind seems to sneak up on us and cause us to act out, over-reacting, toward percieved threats (real and not) before we can stop it. Before we can calm ourselves down enough to be concious of our state of being. It is extremely difficult for us to differentiate this state from legitimate c-PTSD panic attacks and anger, even to the point of not being sure if we've ever had the latter. In theory someone living with us should be able to spot it, or maybe even a support animal. But we cannot obtain either in our current living situation. We have met and heard from others with mast cell disorders who say a panic attack kind of state is a common reaction to histamines for people with them. But none have recognized our extreme paranoia- the often seemingly irresistible compulsion, to falsly see someone/thing else as the cause of the entire reaction. Which always ends when we remove enough histamines (via diet and medication). Let alone been able to advise us on how to handle our emotional reaction to this in the moment and after, or how to discuss this with others. So what is this? Can anyone please help us understand this?

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 #MedMastodon https://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/

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.
