Brief Summary
The goal of this clinical trial is to examine if non-invasive brain stimulation (NIBS) can enhance cognitive function with chronic obstructive pulmonary disease (COPD) population. The main questions it aims to answer are:
- What is the possibility effect of using the NIBS on cognitive functions as well as the cardiopulmonary parameters in COPD population?
- What is the relation between cognitive function parameters and cardiopulmonary parameters in COPD population who suffer from cognitive impairment (CI)? Researchers will compare NIBS to a sham-NIBS to see if NIBS works to improve cognitive function in COPD population. Participants will: Receive NIBS or a sham-NIBS 5 sessions/week for 3 weeks for 20 min each session. Visit the clinic at the beginning for baseline assessment then after the completion of the 3 weeks to reassess them. Outcome measures for cognitive parameters and pulmonary parameters will be taken pre and post NIBS intervention

Outcome Measures
Primary Outcomes (1)
The battery of neurocognitive tests
• Neuropsychological tests are going to be utilised to evaluate cognitive function. • The two key domains to be evaluated are memory and attention. • The Flanker Task will test the attention domain by examining how well the executive control network can be modulated by focusing on one stimulus while concurrently preventing the detection of another stimulus. • The Memory Automaticity Task will be used to evaluate working memory, requiring participants to complete Sternberg-style memory searches in order to attain automaticity; Recalling the existence of a specific letter in the memory set and accurately classifying it are prerequisites for this task. - The previously trained researcher will administer the test.
At enrolment as baseline assessment and at the end of treatment at 3 weeks

Study Arms (2)
Non-invasive brain stimulation
EXPERIMENTALSinusoidal current used between two electrodes on the dorsolateral prefrontal cortex (DLPFC) area. - Gamma-Transcranial Alternating Current Stimulation (tACS) of 2 mA at 40 Hz will be given to the experimental group. - Session duration will last 20 minutes, of 5 session/week, for 3weeks.
Sham Non-invasive brain stimulation
SHAM COMPARATORSinusoidal current used between two electrodes on the dorsolateral prefrontal cortex (DLPFC) area. - To maintain this stimulation's indistinguishability from the experimental stimulation, the control group will be given an electric current that ramps down 60 seconds after the stimulation begins. - Session duration will last 20 minutes, of 5 session/week, for 3weeks.
Interventions
Non-invasive brain stimulation (NIBS) modifies brain activity without surgery using electric currents. - Transcranial alternating current stimulation (tACS) is one type of NIBS that modifies neuronal oscillations in the brain by applying alternating electrical currents to the scalp through electrodes. - This method can enhance motor abilities, improve cognitive functions, and be used in rehabilitation. - It does this by entraining neurones, which synchronise their firing to the applied sinusoidal frequency. The electric current used as ramps down 60 seconds after the stimulation begins.

Eligibility Criteria
You may qualify if:
- Adult age from eighteen years old and above.
