Alexia without agraphia

[@mydisorderedbrain8607]

I'm a PhD candidate and I had a stroke 6 months ago. The damage is to my left angular gyrus. I have Alexia and agraphia and I'm beginning to make videos about my experience. It's so helpful to me to name it and define it. Thank you for this!

Did you get your PhD?

[@Kate-fz3rp]

Dr. Lee, after watching your INO video over a year ago, the algorithm sends me to you whenever you have an answer for the step content I am studying. Your videos are always clear and concise and I'm happy to see them pop up. You are a fantastic educator and we are thankful for your time.

I have alexia without agraphia for years now, and although I am able to understand this phenomenon, I have a little trouble spelling it out for others to understand the details of my injury. Your short KZbin video here is something I can send this link to others so that they can be interested in this a little bit better. THANK YOU!

Dr does all macula spared since it got supplied from other resources ?

[@laluman89]

Finally understood this. Thanks!

After I hit my head, I had episodes where I couldn't read or formulate my thoughts and ideas with words. I could write them down by hand though. I also got colorful orbs in my vision for a few seconds before it happened. That was an interesting year.

My husband is suffering with the same right now, I am trying hard to get back his reading ability. One day for sure God will give me his blessings

WOW, thank you for that explanation. You made it soo easy. My med school professor made it soo challenging.

Is there any treatment for Alexia in mild cases? Could TMS be used?

[@jasminesilva2338]

Great video, straight to the point! Thank you

[@DrPrernaSinha]

Awesome explanation

[@HarryPotter-vl3pc]

Awesome sir ❤️❤️, u didn't mention about macular sparing in PCA Infarct

[@muhammedonel3644]

you are a true treasure sir!

I have Alexia without Agraphia. Hoping to find a way to cure or heal the left hemisphere of my brain.

[@martinlutherkingjr.5582]

Did you find anything?

[@jaklevab6308]

Great videos! Quick question: Given that the macula projects to both hemispheres and that there is typically macular sparing, how is it possible to have alexia without agraphia from lesions to the corpus callosum and the left visual area (pca territory)? Shouldn’t the macular sparing occurring on the left hemisphere be able to cope with the visual field lost ?

Hi, can you do a more detailed video on nystagmus?

[@Helloomi97]

Thank you!!

[@e.s.l.6634]

This is so cool!

[@daintydreze]

Very informative, perfect.

[@blackjglful]

awesome!!!

Thank you, Dr Lee! I've had a brain tumor removed in 2020. The gamma-knife 'clean up' of the site resulted in the eventual development of 'radiation necrosis' in 2022. Both events took place in my left occipital lobe, and each resulted in a craniotomy. In 2020, I didn't even realize my worsening right-side field of vision loss was related to the tumor. My vision seemed to improve after the surgery. In 2022, the familiar vision loss re-occurred, which led to the detection of the necrosis, and the 2nd craniotomy. Unfortunately, this event has left me with a permanent Right Homonymous Hemianopia, and Alexia w/o Agraphia. Fortunately, you have provided me with an explanation of what's happened. Thanks again!

Question: does alexia only occur as a result of a stroke?

[@ahmedelsakka9548]

why can he write ??!! he will see his writing by right side occipital cortex still !!

[@andrefranciscocoutodias3663]

From what I've gathered, alexia stems from a primarily visual problem so to speak. But, writing (grafia) is a primarily motor task, and as such its pathophysiology more closely follows that of other apraxias (localized more in the frontal lobe and associated subcortical structures and tracts). So, imagining a patient: You have an idea to write something (prefrontal cortex) or hear a command to write something (temporal lobe - primary and secondary auditory association cortex and Wernicke, etc...). Then, that information is sent to the corresponding hemisphere, depending on what your dominant hand is, to the premotor and supplementary motor cortices that control motor planning (Exner's area, analogous to Broca's area for speech). And from there finally, movement from primary motor cortex with help from secondary motor cortex, cerebellum, basal ganglia, etc... spinal cord, peripheral nerve, muscle, like any other movement. The thing is, the patient will be able to write (assuming his language and motor centers are preserved) and he will be able to see because he has only a right homonymous hemianopia, so he can see the left visual field, and more importantly his macula is hopefully spared. He can see letters but he cannot join those letters to understand what he is writing. This is obviously an oversimplification, but if you are interested you can read this nice article on agrafia. www.ncbi.nlm.nih.gov/books/NBK560722/

And not a word about agraphia :(
