The intake of caffeine related beverages like coffee, tea and energy drinks is on the rise globally across all age groups. Caffeine has been classified as central nervous system stimulant and therefore high dependency to the drug effects the neuro functions of the brain. The article highlights the research studies and findings of cognitive functions affected by continued use of caffeine. They include mood, memory and attention processing speed of different individuals in different age groups (Fiani, et al 2021). For instance, individuals consuming coffee or energy drinks like Red Bull, enhanced their processing speed rather than boosting attention for their tasks.
Findings on the cognitive performance and moods of persons who are highly dependent on caffeine vary within different age groups. Fiani, et al (2021) article shows individuals of 60-70 years did not seem to have any attention deficiency or sharp processing speed; however, with taking two or three cups of coffee there was increased memory and alertness. Consecutive studies with wider age group fraction between age 35- 70 years showed different results when consumption was not limited (Fiani, et al 2021). Majority had increased reaction in real-time events but their memory impaired and also mood fluctuations, with some overly active while others lacking sleep and withdraw like symptoms hours later.

Physical dependence of the body to a drug is established mainly when the user starts showing withdrawal symptoms like constant headaches, hands shaking and convulsing. It is usually dependent on drug consumed (Hart & Ksir, 2018). The body starts building a tolerance capacity immediately a new substance is introduced and with continuous consumption some body organs fail or become ineffective. Immediate withdrawal of a substance to the body affects the normal functioning of the nervous system thus causing imbalances as the body strives for new coping mechanisms. Gradual is recommended such that the body adapts and rids itself of the toxicity and regenerates to recovery.
