Connected speech production in three variants of primary progressive aphasia.
Primary progressive aphasia is a clinical syndrome defined by progressive deficits isolated to speech and/or language, and can be classified into non-fluent, semantic and logopenic variants based on motor speech, linguistic and cognitive features. The connected speech of patients with primary progressive aphasia has often been dichotomized simply as 'fluent' or 'non-fluent', however fluency is ...
متن کاملPatterns of limb apraxia in primary progressive aphasia.
Primary progressive aphasia (PPA) is a syndrome characterized by a progressive language deficit without other dementia features for at least two years (). Other deficits that are likely to co-exist with aphasia, such as apraxia, have only been investigated in a few case studies and only at a rudimentary level for the most part. In this study we investigate the frequency and severity of apraxic ...
متن کاملDominant frontotemporal dementia mutations in 140 cases of primary progressive aphasia and speech apraxia.
BACKGROUND Mutations in three genes [chromosome 9 open-reading-frame 72 (C9ORF72); microtubule-associated protein tau (MAPT) and progranulin (GRN)] account for the vast majority of familial, and a proportion of sporadic, frontotemporal dementia (FTD) cases. Progressive apraxia of speech (PAOS) is a type of FTD characterized by speech production deficits without a known cause. METHODS We there...
متن کاملFluorodeoxyglucose positron emission tomography in Richardson’s syndrome and progressive supranuclear palsy-parkinsonism.
BACKGROUND We hypothesized that postural instability and cognitive decline in patients with Richardson’s syndrome could be a consequence of reduced thalamic and frontal metabolism. Severe Parkinsonian signs in patients with progressive supranuclear palsy-parkinsonism may be reflected by alterations in putaminal metabolism. METHODS Eleven patients with Richardson’s syndrome, 8 patients with pr...
متن کاملTreatment for Apraxia of Speech in Nonfluent Variant Primary Progressive Aphasia
There is a growing body of literature examining the utility of behavioral treatment in primary progressive aphasia (PPA). There are, however, no studies exploring treatment approaches to improve speech production in individuals with apraxia of speech (AOS) associated with the nonfluent variant of PPA. The purpose of this study was to examine a novel approach to treatment of AOS in nonfluent PPA...
