Hi Darwayne

Welcome to NeuroTalk .

Some thoughts which I hope may help:

From what you have written I think that your language skills are very good. The parts of the brain which do language are in a number of places so the probability of a lesion in any of them is small.

You use the term "visual meaning" or similar to describe not being able get a visual image of a word or concept. One of your examples is "hyperventilation". When I typed that word I did not need to use an image of somebody breathing very deeply to know what it means.

This fits with what we understand about use of language - it has been described as "words and rules"; some parts of your brain store words and other parts which do not totally overlap use rules to combine them into well-formed written or spoken sentences. This is a more detailed explanation of why I think the language modules in your brain are fine.

You said that you used high doses of THC for an extended period. I don't think this is a good idea. At your age your brain is still developing. I am not meaning to scare you but at your age prolonged use of high doses of THC is a risk factor for schizophrenia.
