Spelling - a core language skill - is commonly affected in neurological diseases such as stroke and Primary Progressive Aphasia (PPA). We present two case studies of the same spelling therapy (learning of phoneme-to-grapheme correspondences with help from key words) in two participants: one who had a stroke and one with PPA (logopenic variant). Our study highlights similarities and differences in the time course of each indivdual's therapy. The study evaluates the effectiveness and generalization of treatment in each case, i.e. whether the treatment affected the trained items and/or untrained items, and whether or not the treatment gains were maintained after the end of therapy. Both participants were able to learn associations between phonemes and graphemes as well as between phonemes and words. Reliable generalization to untrained words was shown only for the participant with post-stroke aphasia, but we were not able to test generalization to untrained words in the individual with PPA. The same spelling therapy followed a different time course in each case. The participant with post-stroke aphasia showed a lasting effect of improved spelling, but we were unable to assess maintenance of improvement in the participant with PPA. We discuss these differences in light of the underlying nature of each disease.

Studying neurodegenerative diseases has greatly expanded our knowledge of language, speech and emotion as these diseases can affect areas not typically seen with stroke or tumor. Newer imaging techniques such as voxel based morphometry), fluorodeoxyglucose (F18) positron emission tomography and functional magnetic resonance imaging have allowed localization of these deficits and a greater understanding of the language network targeted by these progressive neurodegenerative illnesses. This review illustrates these important points by describing five syndromes, using clinical cases and then noting the anatomy, typical pathology, and proposed pathophysiology. The syndromes are Progressive Nonfluent Aphasia, Semantic Dementia, Logopenic Aphasia, Primary Progressive Apraxia of Speech and Dysprosody of Speech. Clinicians recognizing these syndromes using the associated clinico-anatomic patterns will lead to more accurate diagnosis and improved patient counseling and management. Further, patients may be included in appropriate clinical trials when their doctors are aware of the most likely pathology.

In this article, we explore the symptoms, cause, treatment potential, and supportive services for individuals diagnosed with Primary Progressive Aphasia (PPA). Although it is possible to regain certain cognitive abilities with stroke or brain injury, in PPA, language abilities worsen and other symptoms emerge with time, shortening the lifespan. The goal of speech therapy for PPA is not to regain lost language, but rather to maximize communication for as long as possible. In this article, we offer information and tools for speech-language pathologists to help people living with PPA achieve these goals and improve overall quality of life.
