Brief summary: The project will allow the assessment of the safety and clinical effectiveness of the device for the treatment of cognitive impairment at Alzheimer\&#39;s diease. The technology used in this study is based on the vagal nerve stimulation method used for more than 25 years and approved by the FDA in the treatment of drug-resistant epilepsy, depression and migraine. The study will use a non-invasive device for percutaneous electrostimulation of the vagal nerve. The previous clinical experience described in the literature has shown that vagal nerve stimulation leads to the activation of brain areas responsible for processing and consolidation of the fresh memory, i.e. the memory being impaired in so-called Alzheimer\&#39;s Disease -AD. In relation to currently used methods of cognitive disorders treatment such as pharmacotherapy, the new solution will increase the effectiveness of therapy. In addition, VGuard is a completely non-invasive device that uses percutaneous stimulation, safe for the patient, and stimulation ranges are below the threshold of perception.


Eligibility criteria: Inclusion Criteria:

1. Signed written informed consent prior to beginning study-related procedures.
2. Female and male subjects aged ≥ 60
3. Able to comply with the study protocol, in the investigator\&#39;s judgment.

Exlusion Criteria:

1. Current or past history of: active psychosis, intellectual disability, bipolar disorder, alcohol abuse, addiction to psychoactive substances or any other major psychiatric condition.
2. Current or past history of any neurological disorder other than dementia, such as: epilepsy, stroke, Transient Ischemic Attack (TIA), Huntington\&#39;s disease, Hakim syndrome, Parkinson\&#39;s disease, multiple sclerosis, intracranial hematoma or brain lesions; and history of previous neurosurgery or head trauma that resulted in residual neurologic impairment.
3. Anticancer treatment within 12 months prior to the screening visit.
4. Clinically relevant serious co-morbid medical conditions within 3 months prior to the screening visit, including, but not limited to:

   1. current active or persistent infection
   2. clinically significant cardiac disease including unstable angina, acute myocardial infarction, congestive heart failure (NYHA III or NYHA IV), uncontrolled arrhythmia, uncontrolled hypertension (\&gt; 2nd stage),
   3. severe liver disease
   4. severe renal impairment
   5. uncontrolled diabetes
   6. chronic obstructive pulmonary disease (COPD)
   7. other metabolic, endocrine or systemic diseases affecting the central nervous system (present hypothyroidism), which in the physician\&#39;s opinion may be the cause of dementia.
5. Permanent usage of benzodiazepines or cholinergic drugs.
6. Insomnia
7. Metal implants (excluding dental fillings) or devices such as pacemaker, medication pump, nerve stimulator, TENS unit, ventriculo-peritoneal shunt, cochlear implant, unless cleared by the study MD.
8. A serious communication barrier.
9. Clinically significant abnormalities at screening (Visit A) in laboratory tests, including: vitamin B12 deficiency or other laboratory abnormalities of possible clinical significance should be discussed with Principal Investigator to determine eligibility.

I 0. Positive pregnancy test ( for female of childbearing potential confirmed in medical interview) or is known from medical interview that woman is lactacting or pregnant.

11. Currently in a study of similar investigational device or investigational product which could interfere in study integrity.
