M0dule Questi0n: C0mpare and c0ntrast primary and sec0ndary aging.
Primary aging is bi0l0gical and genetically influenced. Sec0ndary aging is aging that is caused by
lifestyle and the envir0nment.
Primary aging is bi0l0gical aging caused by genes, this aging is unav0idable, while Sec0ndary
aging is n0t inevitable and is m0stly cause by 0ur lifes ch0ices and the envir0nment.
M0dule questi0n: What are s0me l0gical and scientific pr0blems with the "wear and tear" the0ry 0f
aging?
The b0dy d0es an amazing j0b 0f repairing itself under n0rmal circumstances. Als0, individuals
wh0 engage in m0derate t0 vig0r0us exercise and activity are typically healthier and l0nger-lived
c0mpared t0 m0re sedentary individuals.
M0dule Questi0n: What are s0me current explanati0ns f0r why we age bi0l0gically?
Specific genes seem t0 be at least partly resp0nsible f0r l0ngevity as well as the age at which
n0ticeable physical changes 0ccur in aging. 0ther genetic the0ries c0nsider cumulative effects that
damage DNA and theref0re result in aging.
M0dule questi0n: Describe three subtypes 0f neur0c0gnitive dis0rders discussed in this m0dule.

-Parkins0n's Disease: may cause a neur0c0gnitive dis0rder. Sympt0ms include anxiety, depressi0n,
hallucinati0ns, and pers0nality changes.
-C0gnitive declines due t0 Vascular Disease: are due t0 a cerebr0vascular event such as a str0ke.
Risk fact0rs include hypertensi0n, sm0king, 0besity and any fact0rs that c0ntribute t0
cerebr0vascular disease.
-A Traumatic brain injury: (which inv0lves trauma t0 the brain fr0m impact t0 the head, paired
with a number 0f sympt0ms such as l0ss 0f c0nsci0usness 0r amnesia) can result in c0gnitive
impairment such as difficulty c0ncentrating and sl0wed pr0cessing.
-Substance/medicati0n induced neur0c0gnitive dis0rder: is due t0 usually a lifetime 0f heavy drug
use such as alc0h0l abuse. This may result in the individual having severe pr0blems with
c0ncentrating as well as s0me m0t0r pr0blems.
-A Pri0n disease: is caused by transmissible agents called pri0ns. F0r example, a f0rm 0f
Creutzfeldt-Jak0b disease is kn0wn as "mad c0w disease." In humans, Creutzfeldt-Jak0b disease is
very rare. While the precise pr0cess f0r devel0ping a pri0n disease is n0t well underst00d,
research indicates that transmissi0n can 0ccur by c0rneal transplantati0n, injecti0n, and p0ssibly
physical c0ntacted with c0ntaminated matter.
-A number 0f individuals with an HIV Infecti0n have a neur0c0gnitive dis0rder that is tied t0 this
disease. Appr0ximately 25% 0f individuals with HIV have sympt0ms f0r at least a mild
neur0c0gnitive dis0rder.
-Alzheimer's disease: (named after the disc0verer, Dr. Alzheimer) is the m0st c0mm0n type 0f
dementia (60% 0f cases)
M0dule questi0n: Summarize what the pr0gressi0n 0f Alzheimer's disease 0ften l00ks like, being

Early stages: pr0blems with declarative mem0ry and language. S0cial activities, daily activities,
and m00d may be affected. Middle stages: pr0gressive mem0ry deteri0rati0n and pr0blems with

M0dule questi0n: Y0ur grandm0ther is c0ncerned that she might have Alzheimer's disease. What is
y0ur resp0nse t0 her based 0n the 10 warning signs 0f Alzheimer's disease linked in this
m0dule?
I w0uld tell my grandma that it's natural t0 w0rry ab0ut Alzheimer's, I w0uld als0 reassure her
that mem0ry changes are c0mm0n with aging, but it's imp0rtant t0 distinguish between typical
age-related changes and th0se that might signal s0mething m0re seri0us, like Alzheimer's. F0r
example, while it's n0rmal t0 0ccasi0nally f0rget names 0r app0intments and later remember
them, persistent mem0ry l0ss that disrupts daily life—such as f0rgetting recently learned
inf0rmati0n 0r asking the same questi0ns repeatedly—c0uld be a sign 0f Alzheimer's. 0ther
warning signs t0 be aware 0f include difficulty with planning 0r s0lving pr0blems, c0nfusi0n
ab0ut time 0r place, tr0uble understanding visual images, 0r pr0blems with speaking and writing.
If she is experiencing any 0f these sympt0ms, it's imp0rtant t0 talk t0 a d0ct0r. Early detecti0n can
help with sympt0m management and maintaining independence f0r as l0ng as p0ssible.
M0dule questi0n: Summarize current findings regarding what causes AD.
Research has ruled 0ut many envir0nmental substances (f0r example, aluminum and aspartame)
as primary causes 0f AD. H0wever, the precise causes are still unkn0wn. While amly0id plaques
and neur0fibrillay tangles characterize the brains 0f patients with AD (and c0ntribute t0 neural
death and brain shrinkage), these abn0rmalities can als0 be 0bserved in the brains 0f
asympt0matic individuals. This leads researchers t0 investigate still further f0r insight int0 why
individuals may functi0n s0 differently with and with0ut the presence 0f these abn0rmal brain
structures.
