Now that you know your brain can be older than your chronological age, you may be wondering how that happens. One of the things that make a brain age prematurely is the buildup of “brain trash” and toxins. Brain trash is a by-product of the work your brain cells do.
Your brain cells are like a hustling, bustling Manhattan. Just like a city gets dirty, your brain does too—filled with residual waste from chemical reactions, environmental toxins, old, damaged cells, and that are no longer needed. Your three-pound brain makes five pounds of trash a year. Normally, it’s recycled or flushed out, but if not, the trash can buildup, causing diminished focus, loss of productivity, and a drastic reduction in overall energy. Simply put, the more trash, the “older” the brain.
There are several ways that your brain gets rid of trash. One way is through sleep. Dr. Nedergaard, a neuroscientist, was trying to understand how the brain repairs itself after an injury. She wanted to investigate how sleep played a role in the repair process. While in deep sleep, her subjects experienced a phenomenon that seemed like something out of a horror movie.
She observed that the brains of the sleeping subjects shrank down to 65 percent of their normal size. Once the brain reduced in size, it began to pulsate in a dynamic rhythm.
Further research discovered that the shrinking process squeezed out the trash, waste, and toxins from the brain cells and created space into which the garbage could drain. Once the debris was squeezed into these empty portals in the brain, while the volume of the brain was still reduced, fluid from the spinal cord plunged into the brain for a brainwash.
In the next section, “How Brain Health Can Affect Your Finances,” we’ll look at specific costs related to brain health.

-The more built-up trash, the “older” the brain
Many different types of trash can build up in the brain. Plaques and tangles are the two most common forms of brain trash found in Alzheimer’s disease. Plaques and tangles can stop communication between nerve cells which can be a part of what causes memory loss.

Sasa kwa kuwa unajua kwamba ubongo wako unaweza kuwa na umri mkubwa kuliko umri wako wa kihistoria, huenda ukajiuliza jinsi hilo linavyotukia. Mojawapo ya mambo yanayofanya ubongo uzeeke mapema ni kuongezeka kwa "vitu vya ubongo" na sumu. Uchafu wa ubongo ni bidhaa ya kazi ambayo chembe za ubongo hufanya. Kwa mfano, ubongo wako unaonekana kama Manhattan yenye shughuli nyingi. Kama vile jiji linavyochafuka, ubongo wako pia hujazwa na taka za kemikali, sumu za mazingira, seli za zamani, zilizoharibiwa, na ambazo hazihitajiwi tena. Ubongo wako wa pauni tatu hutengeneza pauni tano za taka kwa mwaka. Kwa kawaida, ni recycled au flushed nje, lakini kama si, taka inaweza kujenga, kusababisha kupungua kwa lengo, hasara ya uzalishaji, na kupunguzwa kwa kiasi kikubwa katika nishati ya jumla. Kwa ufupi, kadiri taka ilivyo nyingi, ndivyo ubongo unavyokuwa "mzee". Kuna njia kadhaa ambazo ubongo wako unaweza kuondoa uchafu. Njia moja ni kupitia usingizi. Daktari Nedergaard, mwanasayansi wa neva, alikuwa akijaribu kuelewa jinsi ubongo unavyojirekebisha baada ya jeraha. Alitaka kuchunguza jinsi usingizi ulivyohusika katika mchakato huo wa kurekebisha. Walipokuwa katika usingizi mzito, watu aliowafundisha waliona jambo lililokuwa kama jambo lililotoka katika filamu ya kutisha. Uwezo wa ubongo wa watu waliolala ulipungua hadi asilimia 65 ya ukubwa wa kawaida. Ubongo ulipopungua ukubwa, ulianza kupiga-piga kwa mwendo wenye nguvu. Utafiti zaidi uligundua kwamba mchakato wa kupungua kwa ubongo uliondoa taka, taka, na sumu kutoka kwenye chembe za ubongo na kuunda nafasi ambayo taka zingeweza kutiririka. Baada ya mabaki hayo kuingizwa kwenye mifereji hii tupu ya ubongo, wakati kiasi cha ubongo kilikuwa bado kimepunguzwa, umajimaji kutoka kwenye uti wa mgongo ulipita kwenye ubongo kwa ajili ya kuosha ubongo. Katika sehemu inayofuata, "Jinsi Afya ya Ubongo Inavyoweza Kuathiri Fedha Zako", tutazingatia gharama maalum zinazohusiana na afya ya ubongo. "Kama matokeo ya kazi ya chembe zako, ubongo wenye uzito wa pauni tatu hufanya pauni tano za taka kwa mwaka. ""Kama taka nyingi zimejengwa, ubongo ni mzee zaidi.""" Vipande na vifungo ni aina mbili za kawaida za taka za ubongo zinazopatikana katika ugonjwa wa Alzheimer. Plaques na tangles inaweza kuacha mawasiliano kati ya seli za neva ambayo inaweza kuwa sehemu ya nini husababisha hasara ya kumbukumbu. Daktari Marc Milstein ni mtafiti mashuhuri wa sayansi ya neva, afya, na furaha. Maoni yake hutoa suluhisho za kisayansi ili kuweka ubongo wenye afya, kupunguza hatari ya dementia, kuongeza uzalishaji na kuongeza urefu wa maisha. Alipata Ph.D. yake katika Biolojia ya Kimia na Shahada yake ya Sayansi katika Molecular, Cellular, na Biolojia ya Maendeleo kutoka UCLA.
