Executive functioning in alcoholics following an mHealth cognitive stimulation program: randomized controlled trial

Area of Science:

• Neuroscience
• Psychiatry
• Digital Health

Background:

• Alcohol dependence leads to severe physical and neuropsychological deficits, particularly affecting the prefrontal cortex.
• Conventional cognitive interventions are effective but often impractical due to time, cost, and patient motivation.
• Existing alcohol treatment protocols help minimize withdrawal symptoms and support general cognitive function.

Purpose of the Study:

• To evaluate the cognitive effects of a novel neuropsychological intervention using mobile technology and serious games (mHealth) in patients with alcohol dependence.
• To compare the efficacy of mHealth intervention against a control group receiving treatment-as-usual.

Main Methods:

• A two-arm randomized controlled trial involving 68 patients undergoing treatment for alcohol dependence syndrome.
• The experimental group received therapist-assisted cognitive stimulation therapy using mobile serious games for 4 weeks.
• The control group received treatment-as-usual without specific neuropsychological intervention.

Main Results:

• Overall cognitive abilities, mental flexibility, processing speed, and attention improved in both groups.
• The experimental group showed significantly greater improvement in frontal lobe functions compared to the control group.
• The study noted a statistically significant improvement (P=.01) in frontal lobe functions in the mHealth group.

Conclusions:

• Mobile serious games show potential as an effective tool for neuropsychological stimulation in alcohol dependence.
• This mHealth approach can help overcome executive dysfunction associated with alcohol dependence.
• While general cognitive functions improved with standard treatment, mHealth specifically enhanced frontal lobe functions.
