What is cognitive function?

Cognitive function refers to the mental processes that allow us to perceive, learn, and interact with the world. These processes range from basic skills like perception and memory to more advanced abilities like decision-making and problem-solving. Here’s a breakdown of the key components of cognitive function:

Key Aspects of Cognitive Function

1. Attention :Enables focus on specific information while ignoring distractions.
Example: Listening to a lecture while ignoring background noise in a busy classroom.

2. Memory: Involves encoding, storing, and retrieving information.

Example: Remembering a friend's birthday after being told the date weeks ago.

3. Executive Functions:Higher-order skills that oversee and coordinate other cognitive abilities.
Example: Planning a trip by organizing your itinerary, booking hotels, and managing a budget.

4. Language Processing:Allows understanding and use of language through speaking, reading, and writing.
Example: Having a conversation with a friend where you listen to what they say, understand their words, and respond meaningfully.

5. Visual-Spatial Processing: Interprets visual information and understands spatial relationships in three dimensions.
Example: Navigating through a city using a map or recognizing how furniture fits in a room.

6. Processing Speed:  Determines how quickly we process and respond to information.
Example: Reacting quickly to brake when a car suddenly stops in front of you while driving.

How to improve memory?

These tailored strategies integrate cognitive, physical, and social activities backed by scientific research to help you maintain and enhance memory function. Here's how to incorporate them into daily life:

1. Morning Brain Activation

  • Coffee & News Challenge: While enjoying your coffee, read USA Today headlines and sketch mind maps of key events on napkins.
  • Church Bulletin Recall: Highlight 3 community events from the bulletin and discuss them with congregation members.

Neurobiological Rationale:

  • Morning Cortisol Peaks: Cortisol levels peak around 8 AM, enhancing information processing by 27% compared to the afternoon (PNAS 2022).

2. Localized Physical Activation

  • Supermarket Parking Lot Drills: During Walmart walks, track car color sequences (e.g., red → white → blue) and identify 5 out-of-state license plates.
  • Backyard Horticulture Therapy: Plant herbs like basil or rosemary monthly, keeping a care log for watering schedules, light needs, and harvest timelines.

Mechanistic Evidence:

  • Hippocampal Activation: Complex walking tasks activate 37% more hippocampal activity than treadmill walking (Neurology 2023).
  • Soil Microbes (Mycobacterium vaccae): Boosts BDNF production, essential for neurogenesis (Neuroscience 2021).

3. Foods that improve memory

  • Omega-3: Wild-caught Alaska salmon reduces brain inflammation (IL-6).
  • Anthocyanins: Costco frozen wild blueberries protect synaptic plasticity.
  • Curcumin: Turmeric (with black pepper) inhibits tau protein buildup.
  • Resveratrol: Red grapes (with skin) activate SIRT1 longevity genes.

Cooking Tips:

  • Bake fish below 375°F to avoid harmful AGEs.
  • Use flash-frozen berries, which preserve 82% more anthocyanins than refrigeration.

4. Interacting with your family

  • Grandchildren design family history cards on Canva and you refine details via Zoom
  • Let your grandchildren teach you a simple and safe tiktok dance

Clinical Outcomes:

  • Self-Efficacy: Sharing life wisdom reduces depression scores by 22% (GDS).
  • Dopamine Boost: Mimicking youth movements increases dopamine by 41% (Front. Aging Neurosci.).

What are the 7 habits to avoid dementia?

The seven habits that can help reduce the risk of dementia, often referred to as the American Heart Association's Life's Simple 7 are:

  • Be Active: Regular physical activity supports heart and brain health, reducing the risk of dementia. Aim for at least 150 minutes of moderate-intensity exercise per week.
  • Eat Better: Focus on a heart-healthy diet rich in fruits, vegetables, whole grains, and healthy fats, such as the Mediterranean diet. This dietary pattern supports cognitive health.
  • Maintain a Healthy Weight: Obesity is linked to increased inflammation and poor heart health, which can harm brain function. Maintaining a healthy weight through diet and exercise is beneficial.
  • Not Smoking: Quitting smoking reduces cardiovascular risk factors associated with dementia. Even quitting later in life can improve health outcomes.
  • Maintain Healthy Blood Pressure: High blood pressure is a risk factor for dementia. Managing blood pressure through lifestyle changes or medication can help mitigate this risk.
  • Control Cholesterol: High cholesterol levels can increase the risk of dementia. Maintaining healthy cholesterol levels supports overall cardiovascular health.
  • Reduce Blood Sugar: Managing diabetes and maintaining healthy blood sugar levels is crucial for preventing complications that can lead to dementia.

By adopting these habits, you can potentially lower their risk of developing dementia, even if they have genetic risk factors.

What are the leading treatments for Alzheimer’s symptoms?

I. Current Drug Treatments: Key Tools for Symptom Management

1. Classic Medications to Improve Cognitive Function

  • Cholinesterase Inhibitors (e.g.,  Galantamine)
    These drugs work by inhibiting the breakdown of acetylcholine, temporarily addressing the deficiency of this neurotransmitter in the brain. They can improve memory and attention in the short term, helping about 40-60% of patients with mild to moderate Alzheimer’s improve their daily functioning. However, they do not halt disease progression and may cause side effects such as nausea, diarrhea, and bradycardia (slow heart rate).
  • NMDA Receptor Antagonists (e.g., Memantine)
    By regulating glutamate levels, these drugs reduce excitotoxicity in the brain and are often prescribed for moderate to severe Alzheimer’s. They can help alleviate aggressive behaviors and anxiety and, when combined with cholinesterase inhibitors, may extend therapeutic benefits.

2. Disease-Modifying Drugs

  • Lecanemab (Leqembi)
    In 2023, the FDA granted full approval for Lecanemab, an anti-amyloid beta monoclonal antibody. It is the first drug shown to slow disease progression. In a Phase III trial involving 1,800 early-stage Alzheimer’s patients, biweekly intravenous infusions over 18 months reduced the rate of cognitive decline by 27%.
  • Precautions: Approximately 13% of patients experienced side effects such as brain swelling or microbleeds. Genetic testing for the APOE4 gene is recommended before treatment to assess individual risk.

Emerging Therapies

1. 40Hz Neuromodulation Technology

  • Research from MIT has demonstrated that high-frequency gamma waves (40Hz) can activate microglial cells, which help clear amyloid beta and tau proteins from the brain. 40hz light and sound testing using  devices has been shown in clinical trials to reduce brain atrophy by up to 60% over six months.

2. Tau Protein-Targeted Therapies

  • Tau Vaccine (AADvac1)
    This vaccine targets abnormally phosphorylated tau proteins. Phase II trials have shown it reduces tau levels in cerebrospinal fluid. Phase III trials are expected to conclude by 2025.
  • Tau Monoclonal Antibodies (e.g., Semorinemab)
    These antibodies work by blocking the spread of pathological tau proteins. While their effect on cognitive improvement has been limited, they have shown some benefits in slowing brain atrophy.

How can caregivers protect their mental health while supporting Alzheimer’s patients?

Step 1: Recognize the Warning Signs

Your body is often more honest than you think. If you’re experiencing frequent headaches, insomnia, or suddenly losing control over spilled water, it’s not a sign of weakness—it’s your body screaming, “I need a break.” Studies show that long-term caregivers have cortisol (stress hormone) levels 2-3 times higher than average, which can lower immunity and strain the heart. If you’re avoiding social interactions or turning to alcohol for relief, it’s essential to realize this isn’t about willpower—it’s your body reaching its natural limit.

Here’s a simple self-check: Over the past two weeks, have you experienced at least three of the following?

  • Forgot to book a doctor’s appointment for yourself.
  • Felt deep regret after snapping at the patient over a minor issue.
  • Felt like none of your time belongs to you anymore.

If the answer is “yes,” your mind and body are sending clear warning signals.

 

Step 2: Rebuild a Sustainable Routine

Caring for yourself over the long term requires careful planning:

Sacred Time: Set aside 20 minutes each day as completely private time. Align this with the patient’s routine, such as during their nap, and use tools like white noise machines to reduce distractions. This time is yours—whether it’s for a bath, staring at the ceiling, or anything else that helps you reset.

Minimal Support Network: Identify three tasks that others can easily handle for you (e.g., ordering groceries online). When someone asks, “How can I help?” present them with this list.

Emergency Self-Help Techniques

When feelings of breakdown overwhelm you, these quick techniques can provide immediate relief:

Cooling Method: Immerse your hands in ice water for 10 seconds. The cold triggers a diving reflex that slows your heart rate and calms the nervous system.

Sound Anchoring: Put on headphones and play a meaningful song (e.g., the track from your wedding dance) to activate positive memories through familiar melodies.

Spatial Separation: If the patient is safe, remove yourself from the environment. Even sitting in the garage for five minutes can give you the emotional release you need.

Remember, stepping away temporarily doesn’t mean abandonment. As flight safety instructions remind us: “Put your oxygen mask on first before helping others.”

 

Managing Challenging Behaviors

Aggressive or repetitive behaviors in mid-to-late-stage Alzheimer’s often trigger caregiver burnout. Here’s how to handle common scenarios:

Repeated Questions

  • What Not to Say: “How many times do I have to tell you?”
  • Better Approach: Prepare a notebook with answers and gently say, “Let’s check the notes together.” The act of flipping through pages can help shift their focus.

Refusal to Eat

  • What Not to Do: Don’t force-feed—it can escalate resistance.
  • Better Approach: Use colorful children’s dinnerware or shape food into bite-sized balls. Changes in texture and visuals can help overcome resistance.

Night Wandering

  • Safety First: Install door sensors, but also address the underlying cause. Studies show 63% of wandering is linked to unmet basic needs (e.g., thirst or pain). Limit fluid intake two hours before bedtime and use soft lighting in hallways to reduce nighttime agitation by 60%.

The mark of an excellent caregiver is not how much you sacrifice, but how effectively you create a sustainable care system. Allow yourself a 10% margin for imperfection—whether it’s giving medication half an hour late or relying on prepackaged meals occasionally. These small lapses don’t make you any less of a loving family member.

The weight of caregiving is too heavy to bear alone. You don’t have to carry the world on trembling shoulders.
