Have you ever heard of glutamate excitotoxicity? No? Well, settle in for a thread. You're going to need to know about this fascinating (and slightly scary) topic that's essential to understanding brain health. 🧵 (1/30)
Glutamate is an excitatory neurotransmitter. You need some constantly being released and taken up by neurons to keep the brain functioning. It is critical to properly function several brain pathways essential for mood and cognitive function. (2/30)
In the prefrontal cortex, glutamate signaling is necessary for executive functions like decision-making, working memory, and attention. When glutamate signaling is functioning properly, it's a very good thing! (3/30)
Microcytic anemias, which affect all cell lines, can have adverse effects on brain and nervous system health. Iron deficiency #anemia, the most common type of microcytic anemia, can cause #cognitive impairment. 🧵(1/18)
Iron is crucial for #brain function, and its #deficiency can reduce #oxygen delivery to the brain, affecting #cognitive processes like #attention, #memory, and learning. (2/18)
#B12 deficiency, another common cause of microcytic anemia, can also damage the nervous system. (3/18)
Thread Alert 🧵: Let's talk about Parkinson's Disease 1/25 #Parkinsons #neurotwitter
In 2005 there was this study that, although very small, showed benefits. "Unified Parkinson’s Disease Rating Scale scores improved in all five during hyperketonemia" 2/25

It wasn't designed to rule out a placebo effect. But the result should have resulted in excitement and further studies being done. 3/25

A fascinating symptom in #neurology is #Alien Hand syndrome

Simplifying , for carrying out bimanual planned movements, we need a Supplementary Motor Cortex (SMA) (left frontal lobe). This communicates to the opposite side via the corpus callosum. Lesions in any will impair proper bimanual function and cause an “alien limb”#neuroanatomy
Frontal variant (left sma lesion) : Patient will have impulsive groping and difficulty releasing objects
Affects the dominant hand
Can be due to a #stroke, #degeneration
My patient impulsively grabs my hand (with his right hand) despite me telling him not to!

A #runner who would #swing his left arm more than the right
1. I have been running outdoors for two years. Over a period of time, one gets familiar with fellow runners- specially their style, pace & endurance. This post is about one of those runners, who was a regular (like me)😆

2. He had one odd style- he would swing his right arm lesser than the left while #running or #walking.
He would continue in the same style for about 60-70 minutes of his #RUN.
His #pace was excellent- 60 minutes for a 10 km run.

3. Our interaction was limited to "Good mornings".
Six months had passed since I first saw him. At this point, I noted that I could outpace him on a few occasions (I was much slower than him to start with).
I had started to think about possibility of a #neurological #disease.

#eyes becoming smaller in evenings could be a sign of #neurological illness
1. I was seeing the last patient, on what had been a busy Monday. While counselling the patient's attendant (aged 45), I noticed that her left eye was smaller than the right.

2. On enquiry, she confirmed that her eyes were of equal size in mornings, but left eye became smaller as the day progressed. This was the case for the past 4-5 months. She had no other issues. This had been noted by her family members and friends too. An eye check up was normal.
3. I discussed with her that this could be a sign of #myasthenia gravis (MG) and asked for investigations. Repetitive nerve stimulation was normal. However, acetylcholine receptor antibody was high (8; normal value<0.25). The diagnosis of MG was confirmed. CT chest was normal.

As some of you know im suffering weird #neurological symptoms atm. The last week has been pretty awful. One of the weirder symptoms is called micrographia: writing getting smaller and smaller.
↙️ My writing on Tuesday (bad not awful day)

Micrographia in itself *can* be an early sign of conditions like #Parkinsons
In patients with Parkinsons, closing their eyes whilst writing can often help mitigate micrographia

(in my case the rapid onset followed by rapid improvement makes me think / hope its just whatever the fuck is going on with my neuro-immunology not a sign of whats to come...😬)

Good Morning #MedTwitter #neurotwitter #MedEd #Neurotwt #Neuroresidents #NeuroOphthalmology #Neuroimmunology #twittorial. Let's have a quick review on #OpticNeuritis and #NMO - Grab a #coffee and let's Start!
1/ Classic #opticneuritis is characterized by a sub-acute loss of vision in one Eye, with central #scotoma, pain on #eyemovement, positive #RAPD

- Age range 15-45 years

- #MOG IgG serum titers depend on disease activity and is mainly from extrathecal origin, enters #CNS from systemic circulation and reaches CSF through passive diffusion or broken #BBB

Awesome study used mice + human brain organiod model to show #COVID-19 can infect the CNS/#brain, where it specifically infected radial #glia, neural stem cells + #neurons. The #virus altered the #metabolism of the neurons it infected + cld use neuron cell machinery to replicate
2/ It’s not surprising that #COVID-19 can infect neurons given the nasal cavity is connected to the #CNS via the cribriform plate, olfactory epithelium + #nerve. This led the team to state that “the brain should be considered a high-risk organ system upon #respiratory exposure”
3/ The team also showed that, at least in some #COVID-19 patients w/ #neurological symptoms, there is a robust antibody response to the #virus in the #cerebrospinal fluid (CSF). In fact, CSF-containing antiviral #antibodies blocked COVID-19 infection in brain organoids
Important 👉 This team is investigating bacterial quorum sensing peptides (QSPs) as metabolites that can contribute to #microbiome-driven disease processes👆They identified QSPs that selectively influence functionality of several types of neuronal #brain cells including microglia
Their abstract concludes that 👉 "Combined with our in-vivo studies indicating that these QSP are permeating the #intestinal wall, as well as the blood-brain barrier, our findings may open up a new field of diagnostic and therapeutic approaches for #neurological disorders."
Rob Moir describes a similar phenomenon in this interview, stating 👉 "#Vagus Nerve traffic may include #bacterial signaling molecules called quorum sensing molecules. In this sense microbes in the gut and microbes in the brain may be “talking...": microbeminded.com/2017/12/18/int…

Incredibly important hypothesis piece published today 👉 “Proposed here is a theory that #microorganisms from within the #brain and elsewhere in the body contribute to the long-term #neurological deterioration characteristic of traumatic brain injury”: sciencedirect.com/science/articl…
Yet another team ties #neuroinflammation to persistent brain infection 👉 Here, RNA seq + western blot + antibody testing identified pegvirus inside the #brain cells of two patients who died from encephalitis (and not controls): folio.ca/u-of-a-scienti…
Important that pegvirus acted as an intracelluar #pathogen (viral antigens were found inside glial cells + lymphocytes + astrocytes)☝️..w/ their presence in lymphocytes suggesting the “cells might serve as a Trojan horse for #viral infection of the brain parenchymal cells.”
Also important is that detection of #pegvirus-antigen in the pre-transplantation bone marrow biopsy of one subject 👉 “indicated that this patient was infected at least 15 years before #neurological presentation, suggesting a period of viral latency.”
