Problem Statement
Alzheimer’s disease (AD) is the most common cause of brain
dementia among elderly.
Currently, there is no single clinical test available for accurate
diagnosis of AD.
Study has shown that Electroencephalography (EEG) has
potentials in differentiating between healthy elderly and probable
AD patients
Unfortunately EEG systems are very expensive to be a viable
options in clinical setups in developing countries like Pakistan
Efficacy of low-cost EEG Systems in measuring EEG Signals for
diagnosis of AD is yet to be tested

3. Aims & Objectives
• There is No single test for Alzheimer’s Disease
• Physicians, often seek help of specialists
Such as neurologists and geriatricians
• A thorough medical evaluation includes
Obtaining a medical and family history from the individual, including cognitive
and behavioral changes
Asking a family member to provide input about changes in thinking skills and
behavior
Conducting cognitive tests and physical and neurologic examinations
Having the individual undergo blood tests and brain imaging to rule out other
potential causes of dementia symptoms, such as a tumor or certain vitamin
deficiencies.

6. Methodology
Devices:
EEG Headset, Neuro Scanner, Electrolyte Gel
Software:
Matlab, SKAN software
Procedure:
1. Subject was asked to sign Consent form
2. EEG cap was placed on his/her head
3. Data was recorded for 20 minutes, it was
comprised of 2 sessions and of 4 segments
each with 5 minutes
4. All the data was stored in SKAN software for
further analysis

7. Data Collection Protocol:
Neuro sensing setup
EEG Headsets
Recording EEG signal
Applying soft tools on recorded data
Also analyzing blood samples on the basis of Neuro proteins.
Interpreting results from collected data

8. CHALLENGES:
Problems:
Oily skin
Dandruff
Long Hairs
Subjects were old
They feel severe pain in prolong sitting, so we helped them with
massage
Electrolyte gel was not viscous, as a result the probability of
interconnection of electrodes was great. Which leads to emergence
of false data
Covide factor played role, as a result our data collection is in
progress

11. Remaining Work
Now we are in our first phase of data collection. After this phase we will
jump towards second phase
Second phase is related to BDNF
Our data collection is in progress (Covide Lockdown)
Then we will go for data Comparison/Analysis
Department of Biomedical Engineering
12. Expected Results
After literature review, we are highly motivated, that we will be able to
conclude our Problem statement in a positive way.
Which will help us in finding a theory, which could be use in early detection
of Alzheimer Disease.
