Language disorders in dementia come in various forms. For example, issues with language may be gradual and may require the assistance of an experienced physician, speech pathologist, or neuropsychologist. Some dementias, such as frontotemporal dementia, primary progressive aphasia, or Pick disease, have aphasic syndromes that are similar to the aphasic stroke syndromes described above, except that they begin gradually and progressively worsen. If aphasia is the only deficit for two years or more then primary progressive aphasia can be
