Final answer:
Not all alcohol-related cognitive impairments are reversible; chronic drinking can cause lasting changes in the brain, some of which may not be fully reversible even after cessation of alcohol consumption.
Step-by-step explanation:
The statement that all alcohol-related cognitive impairments are reversible if the person stops drinking is false. Chronic alcohol consumption can lead to prolonged changes in the brain, resulting in conditions such as Wernicke-Korsakoff syndrome, a form of brain damage that is often irreversible. Furthermore, alcohol can cause alterations in brain function and structure, including a reduction in brain volume and changes in neurotransmitter systems. Chronic exposure to alcohol leads to compensatory adaptations in the reward circuitry, developing alcohol-related behaviors like tolerance and withdrawal symptoms. Therefore, even after cessation, some cognitive impairments may persist due to the long-term effects of alcohol on the brain.
