[Pre & Post Intervention] MILD COGNITIVE IMPAIRMENT and QEEG
Mild cognitive impairment is an intermediate stage between normal aging and dementia, it shows a decrease in
cognitive function including memory, but the ability to perform daily activities is preserved. It is known that 80%
of patients develop Alzheimer’s dementia disease within 6 years after diagnosis of mild cognitive impairment.
However, even with mild cognitive impairment, there is a difference in the morbidity between Alzheimer MCI, and
None-Alzheimer MCI. This can be distinguished by the Al model based on QEEG learning.
According to preceding QEEG research, EEG shows sensitive changes from when functional deterioration occurs
before severe structural changes happen in the brain. ‘Slowing brainwaves’ is the main feature, and it is observed
with Healthy aging people’s EEG, normal brain waves such as alpha wave is observed.
with Mild cognitive impairment patient’s EEG, slow wave such as theta wave is observed.
with Alzheimer’s dementia patient’s EEG, very slow wave such as delta wave and theta wave are observed.
– Age : 70 / Female / Diagnosed with mild cognitive impairment
– A total of 16 sessions of cognitive reinforcement program intervention training were conducted twice
a week for 8 weeks.
| Band Power – Topomap
In the pre-treatment results, slow-waves such as Delta, Theta, Alpha bands have increased.
In the post-treatment results, A particularly noticeable decrease in delta waves was seen.
| Occipital Alpha Peak
Compared with the pre-treatment result, the post-treatment result showed a tendency to recover to the
normal range through an increase in the occipital alpha frequency from 8.75 Hz to 9 Hz.

Compared to the pre-treatment, delta wave has decreased after the clinical treatment.
