导语:如果父母不幸患上痴呆症,那么子女患病风险有多大?可以说这是每一个病人家属都迫切想了解的问题。就拿痴呆症中占比最大的阿尔茨海默病来说,医学领域对此病的研究在近20年来有了跨越式的进步,阿尔茨海默病如果按照遗传性分类可分为家族型和散发型,其中家族型约占5%,散发型占95%。家族型的子女中每个后代的患病率为1/2。而大多数阿尔茨海默为散发型,那么他们的子女的患病风险是否会增加呢?让我们来看看最近发表于神经病学杂志的这篇文章摘要。 神经病学Neurology杂志上发表了一篇研究文章。在以人群为基础的队列研究中,研究那些父母有痴呆症病史的受试者,他们的发病风险与父母的发病年龄和性别之间的相关性。 Parental family history of dementia in relation to subclinical brain diseaseand dementia risk ABSTRACT Objective: To determine theassociation of parental family history with risk of dementia by age at onsetand sex of affected parent in a population-based cohort. Methods: From 2000 to 2002, weassessed parental history of dementia in participants without dementia of theRotterdam Study. We investigated associations of parental history with risk ofdementia until 2015, adjusting for demographics, cardiovascular risk factors,and known genetic risk variants. Furthermore, we determined the associationbetween parental history and markers of neurodegeneration and vascular diseaseon MRI. Results: Of 2,087 participants (meanage 64 years, 55% female), 407 (19.6%) reported a history of dementia in eitherparent (mean age at diagnosis 79 years). During a mean follow-up of 12.2 years,142 participants developed dementia. Parental history was associated with riskof dementia independently of known genetic risk factors (hazard ratio [HR]1.67, 95% confidence interval [CI] 1.12–2.48), in particular when parents werediagnosed at younger age (<80 years:="" hr="" 2.58,="" 95%="" ci="" 1.61–4.15;="" ≥80="" years:hr="" 1.01,="" 95%="" ci="" 0.58–1.77).="" accordingly,="" age="" at="" diagnosis="" in="" probands="" washighly="" correlated="" with="" age="" at="" diagnosis="" in="" their="" parents="">80><80 years="" (r ="0.57, p =" 0.001)="" but="" not="" thereafter="" (r ="0.17, p =0.55)." among="" 1,161="" participants="" without="" dementia="" with="" brain="" mri,="" parental="" historywas="" related="" to="" lower="" cerebral="" perfusion="" and="" higher="" burden="" of="" white="" matterlesions="" and="" microbleeds.="" dementia="" risk="" and="" mri="" markers="" were="" similar="" forpaternal="" and="" maternal="">80> Conclusions: Parental history ofdementia increases risk of dementia, primarily when age at parental diagnosisis <80 years.="" unexplained="" heredity="" may="" be="" attributed="" in="" part="" to="" cerebralhypoperfusion="" and="" small="" vessel="" disease.="" we="" found="" no="" evidence="" of="" preferential="" maternal="" compared="" to="" paternal="">80> 关爱父母 关注阿尔茨海默病 了解阿默延缓及预防组合 |
