Logopenic progressive aphasia

Title

Other Names:

Categories:

Nervous System Diseases

This disease is grouped under:

Primary progressive aphasia

Summary Summary

Logopenic progressive aphasia (LPA) is a type of dementia characterized by language disturbance, including difficulty making or understanding speech (aphasia). It is a type of primary progressive aphasia (PPA). Affected individuals have slow, hesitant speech due to difficulty retrieving the correct words, names, or numbers. Difficulty with phase and sentence repetition are additionally present. Speech is typically well articulated and grammatically correct with good single-word comprehension. But over time, affected individuals may have trouble understanding long or complex verbal information, due to problems holding onto lengthy information that they hear. Language difficulties associated with LPA are due to shrinking, or atrophy, in the left posterior temporal cortex and inferior parietal lobule.

Treatment Treatment

Although no medications or interventions have demonstrated long-term stabilization of logopenic progressive aphasia (LPA), different treatment methods have shown promising short-term benefits.^[2]^[4] Studies utilizing language therapy and behavioral interventions have shown encouraging results. Neuromodulation through methodologies such as Transcranial Direct Current Stimulation (tDCS) and transcranial magnetic stimulation (rTMS) have additionally been identified as a promising therapies to potentially use in combination with behavioral treatment and language therapy.^[2]

As the most common underlying pathology of LPA is Alzheimer's disease (AD) pathology, limited research has been completed on interventions shown to reduce the rate of decline in cognitive symptoms in AD. So far cholinesterase inhibitors and memantine, medications used in Alzheimer’s disease, have not been proven effective in treating logopenic progressive aphasia. Case studies involving steriod use and Omentum Transposition Therapy have reported improvement; however, the results have not been replicated in other cases and as with other treatment options, long-term studies are lacking.^[2]

Prognosis Prognosis

Typically during the first few years following disease onset, signs and symptoms primarily involve speech and language problems. Pronounced behavioral problems are not as common in logopenic progressive aphasia, as in other forms of primary progressive aphasia.^[5] Caregiver experience of changes in behavioral symptoms and everyday skills has been demonstrated to be similar to that of Alzheimer’s disease.^[6]

Little is known regarding the overall life expectancy of individuals with logopenic progressive aphasia. This dementia is associated with Alzheimer’s disease in the majority of cases.^[6] Life expectancy for people with Alzheimer’s disease has been estimated to be between 3 to 10 years.^[7] However, due to the many variables that influence life expectancy, making individualized life-expectancy predictions can be very difficult.
