Progressive Nonfluent Aphasia – An Overview

Progressive Nonfluent Aphasia

This disorder is the rare form of Frontotemporal Dementia. As mentioned, this severely affects the patient’s ability to speak fluently. They mostly exhibit a difficulty with communication due to labored and slow production of words. Also, this is associated with distorted speech and producing wrong word.

A few patients experience slurred speech whereas some others can articulate words but frequently produce near misses. For example, they pronounce the word “sister” as “silter.” They can understand the word meanings, but people with PNFA face difficulty in comprehending sentences. Also, they can’t follow conversations, more importantly when there are multiple speakers. They find it especially hard when they have to communicate with groups of people and use the telephone.

Other Features of Progressive Nonfluent Aphasia

From an early stage, spelling is impaired and a few patients even develop reading problems. This is known as dyslexia. Also, from an early stage, the patients experience subtle deficits in decision making, mental flexibility and problem solving. Behavioral changes are rare in the early stages, although they do occur in the later stages.

A few patients develop apraxia, which is characterized by the clumsiness of handuse. As the disease progresses gradually, it spreads to the frontal lobes of the brain. Hence, several features mentioned above, most importantly changes in empathy and emotional responses occur. These features include:

  • Agrammatism (using the wrong word or tense order)
  • Phonemic paraphasia (sound errors like ‘gat’ for ‘cat’)
  • Anomia
  • Stutter
  • Speech ‘apraxia’
  • Effortful, hesitant speech
