Physicians with specialty in geriatrics, psychiatry and neurology have not received training about the differential diagnosis of dementia, particularly regarding fronto-temporal dementia (FTD). Objective: To assess the level of knowledge of physicians about FTD. Material and Method: The survey was carried out during symposiums and scientific congresses from January 2016 to July 2017. Inclusion criteria: being a general practitioner or specialist in Geriatrics, Neurology and psychiatry whose training process as a physician and specialist has been carried out in Peruvian universities. We analyzed 217 surveys of which 13 were eliminated. The survey was divided into three parts, the first about general data of doctors, the second part was about the diagnosis of dementia; and the third on specific data of FTD. STATA version 12 was used for the statistical analysis. Results: 90% of the doctors surveyed were specialists in: Psychiatry (41.3%), Geriatrics artículo de investigación Recibido: 14/01/2017 Aceptado: 28/03/2018 Los autores no presentan ningún tipo de conflicto de interés.

ObjectiveThe aim of this study was to evaluate caregiver burden based on Zarit Burden Interview (ZBI) and depression in caregivers on the Beck Depression Inventory-II (BDI-II).MethodsLiterate individuals, 18 years or older, who spoke Spanish as their native language were included. Demographic characteristics: Age, sex, education, relationship to person with dementia, length of time caregiving, other sources of help for caring, impact on the household economy, family support, and perception of impaired health; and Clinical data on care-recipients: type of dementia, time since diagnosis, treatment, and Global Deterioration Scale (GDS); the ZBI and BDI-II. Descriptive and analytical statistics were employed to assess caregiver burden and predictors of higher burden in caregivers.ResultsA total of 92 informal caregivers were evaluated. Regarding care-recipients, 75% were 69 years old or over, 75% had at least one year since diagnosis, 73.9% had Alzheimer's disease, 84.8% received treatment, 75% scored 5 or over on the GDS. For caregivers, 75% were 55.5 years old or over, predominantly female (81.5%), married (83.7%), the spouse of care-recipients (60.87%), had at least 10 years of education (75.0%) and one year of caregiving (75%), reduced entertainment time (90.2%) and self-perception of impaired health (83.7%). Median score on the ZBI was 37.5 (minimum value = 3; and maximum value = 74). The coefficient of BDI was 1.38 (p-value <0.001).ConclusionThis sample of Peruvian informal caregivers showed elevated ZBI values. Self-perception of worsened health, repercussion on the family economy and time caregiving were the main determinants of ZBI, although only BDI was a consistent predictor of ZBI.

Presentamos dos casos de demencia de inicio antes de los 65 años de edad con apraxia y manifestaciones visuoespaciales, en los cuales no hay trastornos de memoria y de la conducta, y con diferentes grados de evolución a demencia. Las imágenes estructurales del cerebro demuestran atrofia parieto-occipital. Ambos casos reúnen los criterios de atrofia cortical posterior (ACP).

Depresión y demencia, sobre todo enfermedad de Alzheimer (EA) son entidades críticas en la salud mental de la tercera edad. Ambas condiciones disminuyen la calidad de vida e incrementan el deterioro de actividades de vida diaria de individuos de la tercera edad. EA tiene pobre pronóstico al ser una enfermedad neurodegenerativa; mientras que la depresión es básicamente reversible. Los estudios de seguimiento longitudinal y de caso-control reportan una estrecha asociación entre depresión de inicio tardío y deterioro cognitivo progresivo, pues se ha demostrado riesgo de incremento en 2 a 5 veces para desarrollar demencia en pacientes con depresión de inicio tardío. Por otro lado, la depresión de inicio precoz ha demostrado en forma consistente ser también un factor de riesgo para demencia, y escasas probabilidades de ser pródromo de demencia.La naturaleza de la asociación (si depresión es un pródromo o consecuencia de demencia, o un factor de riesgo para desarrollar demencia) permanece aún sin ser esclarecida. Independiente de ello, las estrategias para tratar depresión podrían alterar el riesgo de desarrollar demencia.
