| Abstract: | Objective: Approximately 50% of patients with amyotrophic lateral sclerosis (ALS) experience cognitive decline, with frontotemporal dementia (FTD) accounting for up to 15% of these cases. Despite this, there is considerable delay in diagnosis, which affects patient care. Methods: We report longitudinal results of neuropsychological evaluations in a patient diagnosed with non-fluent/agrammatic primary progressive aphasia (nfvPPA) and amyotrophic lateral sclerosis (ALS). The patient, Ms. X, presented with progressive speech difficulties starting in her late-60's. Initial diagnosis was nfvPPA. After 4–5 years of progressive swallowing difficulties, as well as facial weakness, her diagnosis was modified to PPA-ALS. Results: Ms. X underwent neuropsychological evaluations three times over a period of five years. Results of evaluations were intact and stable over time, except for progressive loss of speech impacting her performance on a sentence repetition task. Conclusion: This case study provides valuable insight into the overlap between PPA-ALS from a neuropsychological standpoint. The results reflect preserved cognitive skills in the context of loss of speech and motor abilities. This case study also shows the length of time between onset of symptoms and clear diagnosis, which often requires an immense amount of health literacy and personal advocacy on the part of the patient.
