Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in developed countries. [3]
A traditional approach requires treatment beginning at the level of breakdown – in the case of paraphasia, at the level of the phoneme. There are commercially available workbooks that provide various activities such as letter, word-picture, or word-word matching, and sentence completion, among other things.
With Alzheimer's disease in particular, interactions with semantic memory produce different patterns in deficits between patients and categories over time which is caused by distorted representations in the brain.

Brain: Brain dysfunction according to type: Apraxia (patterns or sequences of movements) Agnosia (identifying things or people) Amnesia (memory) Aphasia (language) Dysarthria (speech) Spinal cord disorders; Peripheral nervous system disorders (e.g., Peripheral neuropathy) Cranial nerve disorder (e.g., trigeminal neuralgia)
People with damage to the left hemisphere of the brain are more likely to have anomic aphasia. Broca's area, the speech production center in the brain, was linked to being the source for speech execution problems, with the use of functional magnetic resonance imaging (fMRI), now commonly used to study anomic patients. [9]
Conduction aphasia, also called associative aphasia, is an uncommon form of aphasia caused by damage to the parietal lobe of the brain.An acquired language disorder, it is characterized by intact auditory comprehension, coherent (yet paraphasic) speech production, but poor speech repetition.
Brain rot, a 170-year-old concept that has taken on new meaning in the social media age, is the Oxford Word of the Year for 2024. Oxford University Press, the publisher of the Oxford English ...
In addition to active speech therapy, pharmaceuticals have also been considered as a useful treatment for expressive aphasia. This area of study is relatively new and much research continues to be conducted. The following drugs have been suggested for use in treating aphasia and their efficacy has been studied in control studies.
