Cet article a \u00e9t\u00e9 r\u00e9dig\u00e9 par notre blogueuse invit\u00e9e, la docteure Sarah\u00a0Pakzad, Ph.\u00a0D., L.\u00a0Psych., chercheuse du CCNV. <\/em><\/h2>\n

Comme la fragilit\u00e9 augmente le risque de probl\u00e8mes de sant\u00e9, y compris le risque d\u2019hospitalisation, de chutes, d\u2019incapacit\u00e9s et m\u00eame de mortalit\u00e9, une mesure ad\u00e9quate et une description pr\u00e9cise de la fragilit\u00e9 demeurent des priorit\u00e9s tant en recherche qu\u2019en contexte clinique.<\/p>\n

L\u2019indice de fragilit\u00e9<\/a>, l\u2019\u00e9chelle de fragilit\u00e9 clinique<\/a> et le ph\u00e9notype de fragilit\u00e9<\/a> s\u2019av\u00e8rent \u00eatre des outils pratiques dans le domaine de la g\u00e9riatrie; cela dit, peu d\u2019attention a \u00e9t\u00e9 port\u00e9e \u00e0 l\u2019\u00e9valuation et \u00e0 l\u2019am\u00e9lioration de la sant\u00e9 mentale chez les personnes fr\u00eales (Halil et al<\/em>., 2015).<\/p>\n

D\u2019abord, pr\u00e9cisions que la fragilit\u00e9 est d\u00e9j\u00e0<\/em> identifiable par des indicateurs cliniques. Il s\u2019agit d\u2019un \u00e9tat de vuln\u00e9rabilit\u00e9 accrue qui est le r\u00e9sultat d\u2019un d\u00e9clin des capacit\u00e9s fonctionnelles li\u00e9 \u00e0 l\u2019\u00e2ge. De plus, comme la fragilit\u00e9 a \u00e9t\u00e9 r\u00e9cemment associ\u00e9e \u00e0 des troubles cognitifs et \u00e0 la d\u00e9mence, des chercheurs commencent \u00e0 prendre en consid\u00e9ration l\u2019\u00e9tat cognitif et le bien-\u00eatre psychologique des personnes fr\u00eales afin de mieux d\u00e9finir le syndrome de la fragilit\u00e9 (Langlois et al<\/em>., 2012). Non seulement cette information brossera un tableau plus clair de la fragilit\u00e9, mais elle aidera \u00e0 b\u00e2tir une r\u00e9sistance aux troubles cognitifs et \u00e0 am\u00e9liorer la sant\u00e9 mentale des personnes fr\u00eales (Rolfson et al<\/em>., 2013).<\/p>\n

Autrement dit, l\u2019ajout d\u2019une \u00e9valuation des capacit\u00e9s cognitives \u00e0 l\u2019indice de fragilit\u00e9 fournira d\u2019importants renseignements qui manquaient jusqu\u2019alors et qui permettront d\u2019obtenir de meilleurs r\u00e9sultats.<\/p><\/blockquote>\n

Afin d\u2019adresser ce manque, notre \u00e9quipe de recherche a d\u00e9cid\u00e9 d\u2019utiliser des tests neuropsychologiques pour \u00e9valuer la probabilit\u00e9 de d\u00e9mence et aider \u00e0 prodiguer des soins de longues dur\u00e9es appropri\u00e9s aux personnes \u00e2g\u00e9es. Pour ce faire, nous avons \u00e9labor\u00e9 une m\u00e9thode qui a donn\u00e9 naissance \u00e0 un nouvel outil, l\u2019indice de fragilit\u00e9 neurocognitif (IFN).<\/p>\n

Notre premi\u00e8re \u00e9tape a \u00e9t\u00e9 de concevoir cet indice en y incluant \u00e0 la fois des dimensions physiques et neurocognitives. Pour y arriver, nous avons employ\u00e9 des donn\u00e9es provenant de la Canadian Study of Health and Aging<\/a><\/em> dans le but de cr\u00e9er et de valider l\u2019IFN. Les r\u00e9sultats que nous avons obtenus indiquent que l\u2019IFN permet de pr\u00e9dire la d\u00e9mence avec une grande exactitude (de plus de 90\u00a0%).<\/p>\n

Nous avons ensuite \u00e9tabli des normes pour les personnes \u00e2g\u00e9es pr\u00e9sentant de l\u2019hypertension, du diab\u00e8te ou des ant\u00e9c\u00e9dents de maladies cardiaques. Cette \u00e9tape a aid\u00e9 \u00e0 pr\u00e9dire la probabilit\u00e9 que ces personnes soient atteintes de d\u00e9mence et plac\u00e9es en centre d\u2019h\u00e9bergement. Nous travaillons pr\u00e9sentement \u00e0 l\u2019\u00e9laboration de normes pour les personnes \u00e2g\u00e9es qui ne vivent pas avec un trouble neurocognitif ou avec d\u2019autres graves probl\u00e8mes de sant\u00e9.<\/p>\n

L\u2019IFN a l\u2019avantage de pouvoir rep\u00e9rer les personnes qui courent un risque de d\u00e9velopper une d\u00e9mence au sein de la population \u00e2g\u00e9e en sant\u00e9.<\/p>\n

Nous esp\u00e9rons que, gr\u00e2ce \u00e0 nos efforts, l\u2019IFN augmentera la probabilit\u00e9 de diagnostic pr\u00e9coce de d\u00e9mence chez les a\u00een\u00e9s et facilitera l\u2019instauration d\u2019un traitement appropri\u00e9 en temps opportun qui am\u00e9liorera leur qualit\u00e9 de vie et la qualit\u00e9 des soins qui leur sont prodigu\u00e9s partout au Canada.<\/p><\/blockquote>\n
