Aphasia is a clinical syndrome in which the ability to express and understand spoken words is lost due to impairment of abstract signal thinking caused by neurocentral disorders. Aphasia does not include language symptoms due to disorders of consciousness and general mental retardation, nor does it include language, reading and writing impairments due to damage to sensory and motor organs such as hearing, vision, writing and articulation. Deficits in language skills due to learning difficulties caused by congenital or early childhood disorders are not part of aphasia. The main cause of aphasia in adults is most often aphasia caused by trauma or a brain hemorrhage that damages the cerebral cortex and middle gyrus, which leads to the destruction of language areas that control speech and language abilities. Aphasia in children often refers to a lag and lack of language development, which mainly includes deprivation of the language environment. For example, many parents now rarely take their children and leave them to their grandparents. The grandparents do not brew a good language learning atmosphere, but let the child learn some cartoons and TV. This is when the child is not able to develop some language from simple to complex, which leads to a backward vocabulary and symptoms much like aphasia. But these children are not really aphasic, they are just deprived of a language learning environment. There are also infants, toddlers, and children with aphasia, where the lag in language development is caused by intrinsic problems, such as internal metabolism, and some of the now highly publicized autism, which can lead to a lag in language development, with symptoms similar to aphasia. For children who develop these aphasias, speech rehabilitation, language training, vocabulary learning, etc. have achieved poor results. Complex cognitive training, such as structured education, functional training and assessment of cognitive-perceptual impairment, is also required. Therefore aphasia can be taken more seriously by looking at it as a symptom rather than as a diagnosis.
