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.

Willis, 68, was first diagnosed with aphasia in 2022 before being diagnosed with frontotemporal dementia last year. Most people with aphasia are middle-aged or older. Williams turns 60 in July.
Another study found that prognosis of TMoA is affected by lesion size. Smaller lesions typically cause delays in speech initiation; whereas, larger lesions lead to more profound language abnormalities and difficulty with abstract language abilities. [9] Research has shown that treatment has a direct effect on aphasia outcomes. [25]
