Primary Progressive Aphasia and DementiaNorthwestern University Feinberg School of Medicine  Primary progressive aphasia PPA is a form of cognitive impairment that involves a progressive loss of language function. Language is a uniquely human faculty that allows us to communicate with each other through the use of words. Our language functions include speaking, understanding what others are saying, repeating things we have heard, naming common objects, reading and writing. Aphasia is a general term used to refer to deficits in language functions. PPA is caused by degeneration in the parts of the brain that are responsible for speech and language. Download a PDF Summary of Primary Progressive Aphasia PPAPPA begins very gradually and initially is experienced as difficulty thinking of common words while speaking or writing. PPA progressively worsens to the point where verbal communication by any means is very difficult. The ability to understand what others are saying or what is being read also declines. In the early stages, memory, reasoning and visual perception are not affected by the disease and so individuals with PPA are able to function normally in many routine daily living activities despite the aphasia. However, as the illness progresses, other mental abilities also decline. Adults of any age can develop PPA, but it is more common in people under the age of 6. People with PPA can have a variety of different language symptoms and no two cases are exactly the same. Symptoms Causes. Symptoms. People with PPA can experience many different types of language symptoms. In many instances, the person with PPA may be the first to note that something is wrong and the complaints may initially be attributed to stress or anxiety. People with PPA initially experience one or more of the following symptoms Slowed or halting speech. Windows Vista Beta 2 Installation on this page. Decreased use of language.

Speech is effortful and reduced in quantity. Sentences become gradually shorter and word finding hesitations become more frequent, occasionally giving the impression of stammering or stuttering. Pronouns, conjunctions and articles are lost first. Word order may be abnormal, especially in writing or e mails. Words may be mispronounced or used in the reverse sense e.

PPA L Logopenic Subtype A problem with word finding. In contrast to PPA G, speech is fluent during causal small talk but breaks into mispronunciations and word finding pauses when a more difficult or precise word needs to be used. Some people with PPA L are very good at going around the word they cannot find. They learn to use a less apt or simpler word as well as to insert fillers such as the thing that you use for it, you know what I mean, or whatchamacallit. Spelling errors are common. The naming of objects becomes impaired. Understanding long and complex sentences can become challenging but the comprehension of single words is preserved. Website of Michael Foord.

PPA S Semantic Subtype A problem with word understanding. The principal feature is a loss of word meaning, even of common words. When asked to bring an orange, for example, the person may appear puzzled and may ask what an orange means. Speech has very few nouns and is therefore somewhat empty of meaning. However, it sounds perfectly fluent because of the liberal use of fillers. The person may seem to have forgotten the names of familiar objects. Causes. PPA arises when nerve cells in language related parts of the brain malfunction. The underlying diseases are called degenerative because they cause graduallyprogressive nerve cell death that cannot be attributed to other causes such as head trauma, infection, stroke or cancer. There are several types of neurodegeneration that can cause PPA. The two most commonly encountered types are frontotemporal lobar degeneration FTLD and Alzheimers disease AD. Both FTLD and AD can lead to many different patterns of clinical impairments, depending on the region of the brain that bears the brunt of the nerve cell loss. When AD or FTLD attacks the language areas usually on the left side of the brain, PPA results. PPA is caused by AD in approximately 3. FTLD in approximately 6. In contrast, PPA is a very rare manifestation of AD. In the vast majority of patients with AD, the most prominent clinical symptom is a memory loss for recent events amnesia rather than an impairment of language aphasia. PPA is therefore said to be an atypical consequence of AD. The logopenic type of PPA has a particularly high probability of being caused by AD. Specialized positron emission tomography PET scans and examination of the spinal fluid may help to resolve the distinction between the two underlying diseases. Whether or not PPA is caused by AD or FTLD can be determined definitively only at autopsy through examination of brain tissue with a microscope. This can be confusing because for reasons outlined in the previous paragraph, the word Alzheimers can be used in two different ways. The term Alzheimers dementia or Dementia of the Alzheimer Type is used to designate a progressive loss of memory leading to a more generalized loss of all cognitive functions. The term Alzheimers disease as opposed to Alzheimers dementia is used in a different way to designate a precise pattern of microscopic abnormalities in the brain. Sometimes these abnormalities become concentrated in language areas instead of memory areas of the brain and become the cause of PPA. So, while PPA patients dont have Alzheimers dementia, 3. Alzheimers disease. This dual use of the word Alzheimers is confusing, even for the specialist, but is a feature of medical nomenclature that is here to stay. In the vast majority of individuals, PPA is not genetic. However, in a small number of families, PPA can be caused by hereditary forms of FTLD. The most common gene implicated in these families is the progranulin gene GRN. Other, less common genes implicated in FTLD include the microtubule associated protein tau MAPT and a newly discovered gene, chromosome 9 open reading frame 7. C9. ORF7. 2.
