Cognitive decline

What is Cognitive Decline?

Cognitive decline refers to a gradual worsening of brain functions like memory, reasoning, attention, language, problem-solving, and visual perception over time. It is a natural part of the aging process, but can be accelerated by certain medical conditions or lifestyle factors.

Early signs of cognitive decline include:

• Forgetting familiar words or names occasionally


• Misplacing items more frequently


• Having trouble retaining new information


• Difficulty focusing or paying attention


• Taking longer to do routine tasks

If the declines persist and worsen over time, it could indicate mild cognitive impairment (MCI) or eventual dementia like Alzheimer's disease. However, simple lifestyle changes can help slow the progression in many people.

What Causes Cognitive Decline?

• Aging - Gradual loss of brain tissue and connections


• Vascular factors - High blood pressure, diabetes, high cholesterol


• Traumatic brain injury


• Drug and alcohol abuse


• Neurodegenerative diseases - Alzheimer's, Parkinson's

Genetics and family history can also play a role. As we age, our brains shrink in volume, neurotransmitters decline, and plaques and tangles associated with Alzheimer's accumulate. This leads to impaired neuronal communication and cell death over time.

Can It Be Prevented or Delayed?

Yes! Even if you have risk factors, healthy lifestyle choices can help delay cognitive decline by 5-10 years:

• Exercise regularly - 30 mins a day


• Follow a Mediterranean diet rich in fish, nuts and vegetables


• Stay socially and mentally active


• Get enough sleep - 7-8 hours per night


• Manage medical issues - diabetes, obesity, hypertension


• Consider supplements like omega-3 fatty acids
