The Boston diagnostic aphasia examination. Neologisms are commonly encountered in patients with acute cerebrovascular diseases, particularly in those with Wernicke’s aphasia. Non-fluent aphasias encompass the regions anterior to the central sulcus: Transcortical motor aphasia with difficulty in initiating and organising responses, but relatively preserved repetition, Mixed transcortical aphasia in which echolalia (repetition) is the only preserved language skill.

This is the most common type of aphasia, or condition that affects a person’s ability to communicate. An important variable that complicates these deficit associations is the remarkable reorganization of structure-function relationships that often occurs after brain lesions, such that undamaged parts of the brain assume the functions of the damaged part over time, resulting in recovery from even the most severe aphasias (usually only after appropriate language therapy). Localization and neuroimaging in neuropsychology. Nat Rev Neurosci. Individuals with dementia often have language problems, but they also have at least equally severe deficits in episodic memory, visuospatial skills, and/or executive functions (e.g., organization, planning, decision making).
