Thalamic aphasia is not confined to one predefined thalamic lesion location, but language deficits are particularly pronounced in patients with left anterior IALT presenting with a distinct pattern. Aphasia occurs in almost half of patients with focal thalamic lesions.

What are the language skills of a patient with aphasia?

Language Skills Patient demonstrates moderate receptive and severe expressive aphasia and concomitant moderate apraxia of speech as formally measured on the Western Aphasia Battery: Overall Aphasia Quotient: 18.8/100

How is severe aphasia measured on the Western Aphasia Battery?

Language Skills The patient demonstrates severe aphasia and concomitant severe apraxia of speech as formally measured on the Western Aphasia Battery: Overall Aphasia Quotient: 11/100 Spontaneous Speech Score: 1/20 Auditory Comprehension Score: 2.5/10 Naming Score: 0.8/10

How did the patient receive traditional speech language therapy?

The patient received traditional speech language therapy immediately following his injury when he was an inpatient in an acute rehabilitation hospital.

How does the thalamus affect speech?

The lateralization of thalamic functions also affects the motoric aspects of speech production. Left (but not right) ventrolateral thalamic stimulation disrupted speech articulation and increased the expiratory phase of respiration.

What is thalamic aphasia?

Thalamic aphasia is thought to result from disconnection of cortical language centers from the thalamic nuclei. Strokes in these vascular territories may also cause significant neuropsychological deficits predominantly affecting arousal, memory, and personality changes.

Does the thalamus help with speech?

Penfield & Roberts (1959) hypothesized that the thalamus co-ordinated the functions of three cortical speech areas by projection fibres. Through these fibres speech production was achieved.

What type of stroke is a thalamic stroke?

Hemorrhagic Strokes The most common cause of a hemorrhagic stroke is uncontrolled hypertension (high blood pressure). 5 High pressure damages the small vessels, known as lacunae, in the brain over time. Eventually, these small vessels can break open leading to a hemorrhagic stroke known as a lacunar stroke.
