Many dementia subtypes have more shared signs and symptoms than defining ones. We review 8 cases with 4 overlapping syndromes and demonstrate how to distinguish the cases. These include focal cortical presentations of Alzheimer's disease (AD; posterior cortical atrophy and corticobasal syndrome [CBS]), fluent aphasia (semantic dementia and logopenic aphasia), late-onset slowly progressive dementia (hippocampal sclerosis and limbic predominant AD) and rapidly progressive dementia (Creutzfeldt-Jakob disease and limbic encephalitis). Recognizing the different syndromes can help the clinician to improve their diagnostic skills, leading to improved patient outcomes by early and accurate diagnosis, prompt treatment, and appropriate counseling and guidance.

Cerebrovascular thrombosis is among the most critical medical conditions, making early diagnosis and management crucial. Although some symptoms of cerebrovascular thrombosis are typical and lead to early diagnosis, they can sometimes present with rare and unusual symptoms, complicating the diagnostic process. Given the morbidity and mortality associated with these events, it is important to be aware of unexpected symptoms to diagnose and manage these patients more accurately and rapidly.

We investigated semantic cognition in the logopenic variant of primary progressive aphasia, including (i) the status of verbal and non-verbal semantic performance; and (ii) whether the semantic deficit reflects impaired semantic control. Our hypothesis that individuals with logopenic variant of primary progressive aphasia would exhibit semantic control impairments was motivated by the anatomical overlap between the temporoparietal atrophy typically associated with logopenic variant of primary progressive aphasia and lesions associated with post-stroke semantic aphasia and Wernicke's aphasia, which cause heteromodal semantic control impairments. We addressed the presence, type (semantic representation and semantic control; verbal and non-verbal), and progression of semantic deficits in logopenic variant of primary progressive aphasia.

Article Synopsis
- Wernicke-Korsakoff encephalopathy, a condition caused by vitamin B1 deficiency, often affects alcoholics and is characterized by memory issues, eye movement problems, and coordination difficulties.
- A young male patient with a history of alcohol abuse presented with symptoms resembling a stroke, including right-sided weakness and language disturbances, complicating accurate diagnosis.
- Following treatment with intravenous vitamin B1, the patient ultimately made a full recovery, highlighting how this condition can mimic stroke symptoms and posing challenges in emergency medical settings.

Script training is a speech-language intervention designed to promote fluent connected speech via repeated rehearsal of functional content. This type of treatment has proven beneficial for individuals with aphasia and apraxia of speech caused by stroke and, more recently, for individuals with primary progressive aphasia (PPA). In the largest study to-date evaluating the efficacy of script training in individuals with nonfluent/agrammatic primary progressive aphasia (nfvPPA; Henry et al.
View Article and Find Full Text PDFIntroduction: Non-fluent variant of primary progressive aphasia (nfvPPA) is a neurodegenerative disorder with a predominantly speech and language impairment. Apraxia of speech and expressive agrammatisms along with decreased speech fluency and impaired grammar comprehension are the most typical disorder manifestations but with the course of the disease other language disturbances may also arise. Most studies have investigated these symptoms individually, and there is still no consensus on whether they have similar or different neuroanatomical foundations in nfvPPA.
