Alcohol Use Disorder with Neurological Complications and Hypersexuality: A Case Study of Treatment Challenges

Patient demographics and history

A 37-year-old married male from rural Tuticorin, Tamil Nadu, presented with a 3-year history of severe AUD complicated by neurological and behavioral symptoms. The patient had completed secondary education (12th standard) and worked as an industrial laborer before discontinuing work due to his condition. He lived in a nuclear family with his wife and daughter. Patient details are not disclosed to maintain confidentiality and adhere to ethical guidelines.

Clinical presentation

The patient was initially admitted to a psychiatric facility three years prior for alcohol de-addiction treatment. His clinical presentation included treatment resistance with poor medication compliance, persistent alcohol craving and consumption, public misbehavior and disorganized conduct, hypersexuality with inappropriate sexual demands toward his spouse, aggressive behavior toward family members when they interfered, and symptoms consistent with peripheral neuropathy.

Comorbid conditions

The patient had several comorbid medical conditions, including type 2 diabetes mellitus, thyroid dysfunction, and alcohol-induced peripheral neuropathy (neuritis).

Mental status examination

The mental status examination revealed a disheveled appearance with normal eye contact, deficits in facial expression when discussing alcohol or family issues, restless motor behavior affecting both gross and fine motor skills, moderate attention and concentration deficits, poor memory function, irritable mood and affect, audible but stammering speech, poor judgment regarding personal goals and moral values, and fair insight into illness.

Diagnostic assessment

The patient was diagnosed with Alcohol Use Disorder (F10.20 according to ICD-10-CM criteria, corresponding to 303.90 in DSM classification).⁶ The diagnosis was based on continued alcohol use despite significant problems, tolerance and withdrawal symptoms, unsuccessful attempts to cut down or control use, significant time spent obtaining, using, or recovering from alcohol, and social, occupational, and interpersonal problems.

Treatment and management

Neurological complications

Alcohol-induced peripheral neuropathy affects approximately 25%–66% of chronic alcoholics and is primarily attributed to both direct toxic effects of alcohol and nutritional deficiencies, particularly thiamine deficiency.¹¹ The patient’s symptoms of disorganized behavior and poor concentration align with documented neurological sequelae of chronic alcohol abuse.

Behavioral changes and hypersexuality

The association between AUD and hypersexuality has been reported in clinical literature, though the exact mechanisms remain unclear. Alcohol may disinhibit sexual behavior through its effects on the prefrontal cortex and limbic system.¹² This behavioral change significantly impacted the patient’s family dynamics and created additional treatment challenges, as shown in Figure 1.

Treatment resistance and rural challenges

Treatment resistance in AUD is common, with relapse rates ranging from 40% to 60% within the first year of treatment.¹³ Rural settings present additional challenges including limited access to specialized care, social stigma associated with mental health treatment, lack of ongoing support systems, and economic constraints.

Family impact and social consequences

The patient’s condition significantly affected his family, particularly his wife and daughter. The aggressive behavior and hypersexuality created a hostile home environment, highlighting the need for family-centered treatment approaches and protective measures for vulnerable family members.
