Hey
#MedTwitter
!
I'm starting a podcast. The Child Neuro Podcast.
If you're interested in
#childneurology
check it out on Spotify or Apple Podcast.
I'll be discussing neuro topics for parents and people preparing for the
#USMLE
steps. Links are in the tweet below.
I am honored and excited to be part of the
#ANA2022
meeting! I'll be presenting a poster and giving an oral presentation.
I am looking forward to growing and learning from this magnificent event!

and his great love for
#Science
. What an honor to receive a talk from a
#NobelPrize
winner! Thank you for motivating all of us to keep looking for answers in the simple things.

Final Points
-ALS has a clinical presentation with UMN and LMN dysfunctions
-Glutamate excitotoxicity is a possible initiator of the pathogenic mechanism of this disease
9/
Glutamate excitotoxicity is a main pathophysiologic pathway of neuron damage in ALS, which final step is neuronal death. Its etiology resides in glial cells (e.g. Astrocytes and Microglial cells) surrounding the MNs of the spinal cord.
1/
A clinical presentation of a patient with asymmetric limb weakness, dysphagia, fasciculations, and clonus should immediately make us think of ALS. A fatal disease characterized by both Upper and Lower Motor Neurons alteration.
3/
MNs are the largest neurons in the human body. The specific reason why MNs are targeted in ALS remains unknown. The capacity to breathe, speak, and move deteriorates from the start, but the visual, sexual, and sphincter functions remain normal throughout the disease length.
Don’t miss today’s webinar! Dr. Yano will discuss some ways

data on molecular mechanisms of neurogenetic disease can assist the clinician's judgment during diagnosis, prognostication, and treatment.

7/
Reduced expression of those proteins in spinal cord MNs, and the presence of other proteins (e.g. Semaphorin A3, Dynein), increase the number of glutamate receptors (e.g. AMPA, NMDA) in this specific location.
11/
Dysfunction in the astroglial glutamate transporter (EAAT2) seems to be responsible for the mismanagement of this NT. In consequence, an excessive glutamate uptake by the enhanced receptors in the spinal cord initiates abnormal Ca2+ signaling which ends in cell death.
8/
Also related to the variation in those specific proteins, the spinal cord has a lower number of calcium buffers compared to other MNs. Ca2+ buffers are important in the maintenance of a friendly environment against free radicals which may damage neurons.
5/
The main difference may be in characteristics of susceptibility present in the spinal cord motor neurons, and the discrepancy with features of the oculomotor neurons and Onuf’s nuclei motor neurons, which control visual, and sexual-sphincter functions, respectively.
12/
Finally, cell death amplifies excitotoxicity by releasing more glutamate from dead neurons, thus, killing more susceptible neurons. Riluzole, approved in 1995, inhibits glutamate release from neurons and inactivates certain channels protecting neurons from damage.
14/
Final Points
-There are intrinsic susceptibility factors for neuronal damage such as specific proteins subdivided by location
-Riluzole is one of the only two drugs approved to treat ALS, and it is the only one to target glutamate excitotoxicity directly.
