Response to sodium lactate infusion in alcoholics with panic attacks

Area of Science:

• Psychiatry
• Neuroscience
• Addiction Medicine

Background:

• Panic disorder is a distinct psychiatric condition.
• Alcohol use disorder (AUD) can co-occur with or mimic panic symptoms.
• The diagnostic specificity of panic attacks in alcoholics requires further investigation.

Purpose of the Study:

• To investigate the response to sodium lactate infusion in alcoholics with and without a history of panic attacks.
• To compare the panic response in alcohol-dependent individuals to that of nonalcoholic patients with panic disorder.
• To assess the utility of lactate infusion as a diagnostic tool for panic disorder in alcoholics.

Main Methods:

• Sodium lactate infusion was administered to three groups: alcoholics with panic attacks, alcoholics without panic attacks, and nonalcoholic patients with panic disorder.
• The rate and characteristics of lactate-induced panic attacks were recorded and compared across groups.

Main Results:

• Alcoholics with a history of panic attacks exhibited a significantly higher rate of lactate-induced panic compared to alcoholics without panic attacks.
• The panic response to lactate infusion in alcoholics with panic attacks was comparable to that observed in nonalcoholic patients with panic disorder.

Conclusions:

• Lactate-induced panic appears specific to panic states, supporting its diagnostic relevance.
• Panic attacks experienced by alcoholics share similarities with those in nonalcoholic individuals.
• Sodium lactate infusion may serve as a valuable diagnostic aid for identifying panic disorder in the context of alcohol use.
