Semantic Dementia

Semantic Primary Progressive Aphasia


  • In the first experimental condition, the pictures represented personally familiar persons present in a specific spatial and temporal context.[ncbi.nlm.nih.gov]
  • A final step-change in the areas engaged and the quality of recollection then preceded the collapse of autobiographical memory.[ncbi.nlm.nih.gov]
  • Somatic symptom disorder was associated with misidentification and preoccupation with normal bodily sensations such as hunger, bladder filling, borborygmi, rhinorrhea, and reflux; excessive concern over the incompletely understood meaning or source of[ncbi.nlm.nih.gov]
  • The SD group had better face familiarity scores, suggesting a potentially useful clinical test for distinguishing SD from DP.[ncbi.nlm.nih.gov]
Compulsive Disorder
  • We describe a patient presenting with late-onset typical obsessive-compulsive disorder (OCD) that lasted for 10 years as an isolated condition before developing clinical and neuroimaging features of SD.[ncbi.nlm.nih.gov]
  • Here we describe the case of a 71-year-old patient with a typical clinicoanatomical syndrome of semantic dementia led by selective (predominantly right-sided) temporal lobe atrophy, who showed striking amelioration of previously disabling claustrophobia[ncbi.nlm.nih.gov]

  • Wernicke-Korsakoff syndrome; profound retrograde and anterograde amnesia, and to fill in memory gaps, patients CONFABULATE Initial workup of dementia should include complete metabolic profile, including liver function tests and thyroid studies Young pt[quizlet.com]


  • Whereas an abundance of research has been dedicated to treatment for anomia in individuals with focal brain damage due to stroke, considerably less work has been done regarding treatment for patients with progressive language decline.[ncbi.nlm.nih.gov]


  • Prognosis of Semantic Dementia The prognosis is poor. It progresses rapidly and become worse. The semantic dementia causes death in 2 to 10 years from infection and some time from general failure of body systems.[depression-guide.com]
  • Best prognosis tends to be in those with the semantic type, and survival may be as long as ten years or more. Worst prognosis is associated in the overlap syndrome with motor neurone disease, and there may only be 3-5 years between onset and death.[patient.info]
  • What is the prognosis (the outlook) for frontotemporal dementia? The outcome for people with frontotemporal dementia is poor.[medicinenet.com]
  • Further research should be directed at understanding and developing new diagnostic and therapeutic modalities to improve the patients' prognosis and quality of life.[doi.org]


  • Improved reliability of diagnoses will be increasingly important as trials for etiology-specific treatments become available. We also discuss the implications of these syndromes for theories of language function.[ncbi.nlm.nih.gov]

  • Grammar is also diminished, including reduced syntactic complexity13 and fewer subordinate clauses.14 Crucially, whether an individual becomes more impaired in either his or her grammar or word finding can be indicative of the location of the etiology[todaysgeriatricmedicine.com]

  • Epidemiology and Treatment Because the lvPPA has been only recently described (Gorno-Tempini et al. 2004 ), there is still little known about its epidemiology and treatment.[doi.org]
  • Heritability, however, varies with the different clinical subtypes (discussed below). [ 4 ] Epidemiology [ 5 ] FTD is much less common than Alzheimer's disease and vascular dementia.[patient.info]

  • BACKGROUND: Developmental prosopagnosia (DP) and semantic dementia (SD) may be the two most common neurologic disorders of face processing, but their main clinical and pathophysiologic differences have not been established.[ncbi.nlm.nih.gov]
