===Aphasia===
[[Aphasia]] is loss of the ability to produce or comprehend [[language]]. There are acute aphasias which result from stroke or brain injury, and primary progressive aphasias caused by progressive illnesses such as dementia.
* Acute aphasias
** [[Expressive aphasia]] also known as Broca's aphasia, expressive aphasia is a non-fluent aphasia that is characterized by damage to the frontal lobe region of the brain. A person with expressive aphasia usually speaks in short sentences that make sense but take great effort to produce. Also, a person with expressive aphasia understands another person's speech but has trouble responding quickly.<ref name="Sinanović, 2011">{{cite journal |vauthors=Sinanović O, Mrkonjić Z, Zukić S, Vidović M, Imamović K|title=Post-stroke language disorders |journal=Acta Clin Croat |volume=50 |issue=1 |pages=79–94 |date=March 2011 |pmid=22034787}}</ref>
** [[Receptive aphasia]] also known as Wernicke's aphasia, receptive aphasia is a fluent aphasia that is categorized by damage to the temporal lobe region of the brain. A person with receptive aphasia usually speaks in long sentences that have no meaning or content. People with this type of aphasia often have trouble understanding other's speech and generally do not realize that they are not making any sense.<ref name="Sinanović, 2011"/>
** [[Conduction aphasia]]<ref name="Sinanović, 2011"/> also known as association aphasia, is when there is a difficulty repeating words or phrases. Comprehension and spontaneous speech are usually not limited, just repetition. 
** [[Anomic aphasia]]<ref name="Sinanović, 2011"/> is when one has difficulty retrieving words and may take long pauses when trying to recall certain verbs or nouns. This is a mild form of aphasia as comprehension is not limited.
** [[Global aphasia]]<ref name="Sinanović, 2011"/><ref>{{Cite web |title=Global Aphasia |url=https://aphasia.org/aphasia-resources/global-aphasia/ |access-date=2023-12-03 |website=The National Aphasia Association |language=en-US}}</ref> is the most severe form of aphasia as there is difficulty with speech comprehension, as well as difficulty in responding in meaningful ways. This is caused by several brain injuries in more than one spot. 
* Primary progressive aphasias (PPA)
** [[Progressive nonfluent aphasia]]<ref name="Harciarek, 2001">{{cite journal |vauthors=Harciarek M, Kertesz A|title=Primary progressive aphasias and their contribution to the contemporary knowledge about the brain-language relationship |journal=Neuropsychol Rev |volume=21 |issue=3 |pages=271–87 |date=September 2011 |pmid=21809067 |pmc=3158975 |doi=10.1007/s11065-011-9175-9}}</ref> also known as PNFA, is a form of PPA that involves a reduction of speech fluency, syntax and grammar impairment, difficulty of articulation and word finding, and long-term comprehension. 
** [[Semantic dementia]]<ref name="Harciarek, 2001"/> is a condition in which words and phrases slowly begin to lose meaning, and comprehension is lost because of a deterioration in the [[semantic memory]].  This is usually characterized by behavior changes, fluent speech but with no meaning, preserved syntax and grammar, and the impaired ability to recognize objects. 
** [[Logopenic progressive aphasia]]<ref name="Harciarek, 2001"/> also known as LPA, is associated with [[Alzheimer's disease]]. This is characterized by difficulty in word retrieval and repetition, phonological errors, anomia, and the preservation of single-word comprehension.
