#agrammatism

• Acataphasia — A severe neuropsychological speech disorder characterized by the patient's inability to formulate syntactically and grammatically correct sentences, whereas the ability to pronounce isolated words and the comprehension of their meaning remain intact. This symptom typically arises from focal brain lesions or specific neurodegenerative conditions, leading to fragmented, agrammatic, and incoherent expression.
• Agrammatism — A neurological language disorder commonly associated with Broca's aphasia, characterized by the loss of the ability to produce grammatically correct sentences; patients exhibit a telegraphic speech style, omitting functional words such as prepositions, articles, and conjunctions.
• Asyntaxia — A rare language disorder, often of neurological origin, consisting of a person's structural inability to arrange words in sentences according to syntactic rules, resulting in a fragmented speech, devoid of grammatical coherence or reduced to a telegraphic style. This clinical precision phenomenon is encountered in certain forms of aphasia, preventing fluid expression although isolated vocabulary remains partially intact.
