Addressing Drug and Alcohol Related Brain Damage: Counselor Training and Neurocognitive Impact

This podcast episode, hosted by Dr. Donal Snipes, provides crucial training for addiction counselors on the pervasive and often undiagnosed issue of drug and alcohol-related brain damage. It details a range of substance-induced disorders, including persisting amnesic, psychotic, mood, sexual dysfunction, sleep, and dementia, alongside conditions like Fetal Alcohol Spectrum Disorders (FASD), Chronic Traumatic Encephalopathy (CTE), and neurocognitive disorder. The staggering prevalence of brain damage in individuals with substance use disorders, estimated between 30% and 80%, underscores the necessity for counselors to recognize these impairments, even when mental health issues are the primary presenting concern. The episode highlights how such damage significantly impacts physical health (inflammation, sleep, pain, neuropathy), interpersonal relationships (self-efficacy, nonverbal interpretation), emotional regulation (dysregulation, apathy), and cognitive functions (executive functioning, memory, treatment compliance), sometimes necessitating assisted living.

The presentation delves into the specific neurobiological mechanisms and brain regions affected by different substances. Alcohol, for instance, causes systemic inflammation, oxidative stress, thiamine deficiency, excitotoxicity, and neuroinflammation, leading to brain shrinkage in the frontal, parietal lobes, and cerebellum. Stimulants induce dopamine neurotoxicity, neuroinflammation, and oxidative stress, impacting the prefrontal cortex, limbic structures, and basal ganglia. Opioids cause hypoxia, neuroinflammation, and glial cell dysfunction, resulting in atrophy in the frontal cortex, hippocampus, and cerebellum. Inhalants lead to direct white matter toxicity and demyelination, affecting frontal, temporal lobes, and cerebellum. Cannabis, particularly chronic high-dose use, alters the hippocampus and prefrontal cortex through endocannabinoid system dysregulation. A critical distinction is made between willful resistance and symptoms stemming from actual brain damage, emphasizing that healing the brain is paramount for recovery.

Key distinctions are drawn between various neurocognitive disorders, such as Hallucinogen Persisting Perception Disorder (HPPD), Delirium, Wernicke's Encephalopathy, and Korsakoff Syndrome. Wernicke's, caused by thiamine deficiency, presents with sudden disorientation, memory loss, and eye movement issues, requiring immediate medical intervention to prevent progression to Korsakoff Syndrome. Korsakoff is characterized by severe short-term memory loss, inability to learn new information, and confabulation—where individuals unknowingly invent explanations to fill memory gaps. The episode stresses that these conditions are often undiagnosed, especially outside of severe alcohol use, and that alcohol-related brain damage (ARBD) affects 3% of the general adult population and up to 30% of those with alcoholism. It also notes that the DSM-5 TR no longer requires dependence or withdrawal for a substance use disorder diagnosis.

Practical insights include the importance of recognizing heavy drinking (more than one drink/day for women, two for men) and the potential for brain damage even without dependence. Counselors are urged to educate clients and families about confabulation, emphasizing it's not intentional lying. The episode advocates for anti-inflammatory lifestyles, regulated circadian rhythms, healthy diets, and cognitive stimulation to promote neurogenesis and recovery. While acknowledging that abstinence may not be every client's goal, understanding alcohol's profound impact is crucial. The broader implications highlight that ARBD causes over 10% of dementia cases in people under 65, and even moderate drinking increases the risk of Alzheimer's and vascular dementia, with recent reports suggesting no safe level of alcohol consumption. Recovery from ARBD is possible with support and sustained abstinence, but prior use significantly increases the risk of future dementia.

the prevalence of brain damage in people with substance use disorders is estimated to be between 30% and 80%

even if they're primary presenting issue is mental health if they have a substance use disorder there's a really strong likelihood that they've got some level of brain damage as a result

we do need to realize the impact that alcohol has we also need to realize that heavy drinking is considered anything more than one drink a day for women and two drinks a day for men

recognizing that some of this stuff some of these symptoms or behaviors we're seeing are not willful resistance they may be the result of brain damage

we need to heal the brain thing because there's been damage

even years after the insults have stopped even years after the person has quit using we may start to see the symptoms the damage was done back then and the plaques started being laid in the brain

corov syndrome is diagnosed in about one in eight people with alcohol use disorder

those with corov syndrome May confabulate or make up information they can't remember they're not lying but may actually believe their invented explanations

alcohol rated brain damage is greatly undiagnosed postmortem findings indicate that it affects three per 100 of the general adult population

there's possibly no level of alcohol consumption that is safe
