The study will examine whether the effects of computerized brain training are enhanced when training is combined with mild brain stimulation in patients with mild cognitive impairment. We hypothesize that this combination will produce greater improvements in cognitive functioning than computerized brain training alone.

Inclusion Criteria:

• Aged 60 - 85 years.
• Meet diagnostic criteria for amnestic mild cognitive impairment.

Exclusion Criteria:

• Inability to provide informed consent.
• Concurrent medication likely to affect mental performance.
• Current substance use or dependence in last 3 months.
• Current active psychiatric or neurological condition
