Artie delphi goo! Thank you for your checking! Have a nice day!

I agree with Chris (below) as to the pathology. As to the grammar: -"aphasia - Is health condition...": maybe "Aphasia is a health condition..." or "Aphasia: A health condition..." -"...health condition when somebody...": better would be "a health condition *where* somebody..." or "a health condition *in which* somebody..." -"...can't speak or heard...": use "hear" instead of "heard" -"...because the man...": as you used "somebody", we often convert this to the pronoun "they". In older times they might convert "somebody" to "he", but this is used less now. -"...has a damage of a brain part which place in a left frontal lobe of brain...": this needs a lot of work. I would say "...has damaged the left frontal lobe of the brain." I have turned "damage" into a verb, but you can say "...has damage in the left frontal lobe..." or "...some damage..." Damage is a collective noun, and doesn't take an indefinite article "a". Since you are saying "left frontal lobe", which is a part of the brain, you don't need to say "part". If you are referring to a specific place inside the left frontal lobe, you can say "...part of the left frontal lobe of the brain." -"...which place in...": you might mean, "which is located in". -"...of brain.": we would say "of *the* brain". Usually, when we talk about organs of the body in general, we use a definite article.

Thank you a lot for your comment! Regards!

Aphasia is a neurological condition which interferes with the ability to process words (listening comprehension, reading comprehension, written expression, verbal expression).
