Peripheral (Hicks et al., 2015) or intracerebroventricular (ICV) AVP (Le Moal, Dantzer, Michaud, & Koob, 1987) enhance social recognition memory. This effect of AVP on social recognition depends, in part, upon activation of V1aR receptors in LS (Veenema et al., 2012). OT delivered to the posterior BNST did not enhance social recognition memory in female rats (Dumais, Alonso, Immormino, et al., 2016), although OTR antagonist into posterior BNST impaired social recognition memory in both males and females (Dumais, Alonso, Immormino, et al., 2016).

• Thus, cortisol itself either directly or indirectly inhibits the CRH-producing neurons in the hypothalamus and the ACTH-producing cells in the anterior pituitary that control cortisol secretion, thereby blunting overall HPA axis activity and subsequent cortisol secretion.
• Nutrition and lifestyle also influence biological changes in the aging brain, such as nicotine intake and chronic alcohol consumption (Beach et al., 2015).
• Just as a two-way interaction appears to exist between alcohol and aging—that is, (1) aging can modify the body’s response to alcohol, and (2) chronic alcohol exposure can modify the aging process—an analogous two-way interaction also appears to exist between stress and aging.
• For instance, interactions with peers become particularly important during adolescence, with these interactions having a greater impact on decision-making and behavior of adolescents than adults (Gardner & Steinberg, 2005).
• The hippocampus is vitally important for memory formation and, interestingly, has a high concentration of glucocorticoid receptors.

Further, the olfactory system contains a high concentration of δ receptors (Le Merrer et al., 2009). Interestingly, opioid receptors can be found in many of the brain structures that mediate social behavior, including the mPFC, BNST, AMG, and ventral striatum (Le Merrer et al., 2009). Further, motivated- and goal-directed behavior is facilitated by the action of endogenous opioids, not only in the context of drug-seeking (Laurent, Morse, & Balleine, 2015), but also in social behavior (Trezza et al., 2010).

Changes in Cognition in the Aging Brain

Ideally when I drink, I’ll pause and ponder the intriguing viognier in my glass before raising it to my lips. I’ve always been healthy and fit, and I kid does alcohol make you look older myself that a little poison can’t hurt me. Our 20-something daughter fled New York and moved back home, bringing Brooklyn cocktail culture with her.

How much alcohol is safe to drink?

• Researchers are also studying the possibility that alcoholic liver disease might be caused, at least in part, by your immune system attacking healthy body tissues.
• Future research should assess whether social motivation is decreased in aged animals, and whether this may be driven by alterations in opioid or cannabinoid signaling, in addition to examining age-related alterations in OT and AVP.
• Mixing alcohol with opioids or benzodiazepines like diazepam (Valium) is one potentially deadly combination.
• Thus, a more complete understanding of neural systems – including neuroinflammatory processes—which contribute to alcohol-induced changes in social behavior, will provide opportunities and targets for healthy aging.
• For example, older people who received a dose of the potent synthetic glucocorticoid dexamethasone exhibited a blunted negative feedback response (Seeman and Robbins 1994) and thus were exposed to higher overall glucocorticoid levels than were younger people undergoing the same procedure.

It remains to be seen whether these neuropeptide systems are altered in aged animals. Future research should assess whether social motivation is decreased in aged animals, and whether this may be driven by alterations in opioid or cannabinoid signaling, in addition to examining age-related alterations in OT and AVP. In this review, the effects of alcohol on cognitive decline in older adults were addressed. In the following, it was shown that depending on the amount and frequency of consumed alcohol, the results in cognitive tests decline or improve.

If participants consumed alcohol predominantly in social contexts or for social reward it may have led to drinking larger amounts within these social occasions and consequently drinking-related problems were more likely to occur (Sacco et al., 2015). Taken together, the human data demonstrate that social motives for drinking are endorsed by all age groups, with these motives contributing to heavy and problematic drinking. Early studies in Europe and other countries demonstrated 10 to 20 percent reductions in drinking for people receiving a brief intervention compared with people in control groups (e.g., Saunders et al. 1993). In addition, meta-analyses of randomized controlled studies examining the effectiveness of brief interventions find that these techniques generally reduce drinking in the intervention group.

1. Alcohol use and sensitivity across lifespan

• Specifically, screening and brief interventions in a variety of health care and social service settings have reduced alcohol consumption among older adults, with these reductions sustained for 2 to 18 months (Fleming et al. 1997; Moore et al. 2011; Schonfeld et al. 2010).
• Trezza et al. (2011) demonstrated that morphine, an opioid receptor agonist, facilitates play when administered directly into the NAC.
• Each microglia cell maintains a well-established territory of surveillance evidenced by the length of its processes.
• Sickness-related suppression of social behavior is common to most social species and likely evolved as an evolutionary mechanism to control the spread of infectious disease and promote recovery from infection and/or injury.
