Outcome Measures

Primary Outcomes (1)

  • Mini-Mental State Examination (MMSE)

    The Mini-Mental State Examination (MMSE) was used to assess global cognitive status. It evaluates orientation, immediate and delayed recall, attention and calculation, language, and visuospatial construction. The total score ranges from 0 to 30, with higher scores reflecting better cognitive function. Cognitive impairment was classified as mild (21-24), moderate (10-20), or severe (\<10). The MMSE was administered in a face-to-face interview format

You may qualify if:

  • Patients aged from 18 to 70 years.
  • Both sexes.

You may not qualify if:

  • Patients with other non-COVID-related chronic illnesses that could interfere with the assessment of post-viral symptoms.
  • Patients with pre-existing neurological disorders that could affect cognitive function or fatigue assessment, including dementia, Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy, or prior cerebrovascular stroke, patients with diagnosed psychiatric disorders such as major depressive disorder, bipolar disorder, schizophrenia, or anxiety disorders requiring ongoing pharmacological treatment.
  • Patients with uncontrolled endocrine disorders, particularly uncontrolled diabetes mellitus or thyroid dysfunction.
