🩺 Chapter A – Modules 13 to 15 (Combined Medical Conditions)

 

📘 Module 13 – Athlete’s Foot (Fungal Skin Infection)

🦶 What is Athlete’s Foot?

Athlete’s Foot is a common fungal infection of the skin on the feet (tinea pedis). It is not limited to athletes—anyone can develop it.


🌡️ Causes

  • Fungal infection thrives in warm, moist environments
  • Common places:
    • Locker rooms
    • Public showers
    • Swimming pools
  • Wearing tight or sweaty shoes for long periods

🧠 Symptoms

  • Itching between toes
  • Burning sensation
  • Peeling or cracked skin
  • Redness or scaling
  • In some cases, blisters

💊 Treatment & Prevention

Treatment:

  • Antifungal creams
  • Antifungal powders or sprays

Prevention:

  • Keep feet dry
  • Change socks regularly
  • Wear sandals in public showers
  • Avoid sharing footwear

🧩 Key Idea

A simple fungal infection that spreads easily but is easily treatable and preventable.



📘 Module 14 – Atrial Fibrillation (AFib)

❤️ What is AFib?

Atrial Fibrillation is the most common heart rhythm disorder, where the upper chambers of the heart (atria) beat irregularly and rapidly.


⚡ Symptoms

  • Irregular or fast heartbeat
  • Palpitations (fluttering chest feeling)
  • Fatigue
  • Shortness of breath
  • Dizziness
  • Reduced exercise ability

🧠 Causes & Risk Factors

  • Age (risk increases with age)
  • High blood pressure
  • Diabetes
  • Heart disease

🏃 Exercise Link

  • Moderate exercise lowers risk
  • Long-term intense endurance exercise (e.g., marathon running) may increase risk in some individuals

💊 Treatment

  • Medications to control heart rate/rhythm
  • Blood thinners (to prevent stroke)
  • Lifestyle changes
  • Procedures like catheter ablation

⚠️ Key Risk

AFib increases the risk of stroke, making early diagnosis and treatment important.


🧩 Key Idea

AFib is a serious but manageable heart rhythm condition with strong links to lifestyle and cardiovascular health.



📘 Module 15 – Autism Spectrum Disorder (ASD)

🧠 What is Autism?

Autism Spectrum Disorder (ASD) is a lifelong neurodevelopmental condition affecting how a person communicates, processes information, and experiences the world.


🧩 Core Characteristics

  • Differences in social interaction
  • Communication differences (verbal and non-verbal)
  • Repetitive behaviours or routines
  • Sensory processing differences (sound, light, touch)

🧠 Associated Features

  • Strengths in memory, detail, or pattern recognition
  • Difficulty with change or transitions
  • Sensory sensitivities (over- or under-sensitive responses)

🏥 Health Connections

Research shows ASD may be associated with:

  • Increased risk of some physical health conditions
  • Differences in motor coordination (e.g., flat feet in some individuals)
  • Links in genetic research to conditions like atrial fibrillation and heart issues

⏳ Lifelong Nature

  • Autism is not an illness or something to “cure”
  • It is a neurological difference present from birth
  • Support focuses on communication, learning, and independence

🧩 Support Strategies

  • Structured routines
  • Visual supports
  • Communication tools
  • Sensory accommodations
  • Educational support plans (e.g., IEPs)

🧩 Key Idea

Autism is a neurodevelopmental difference, not a disease, and support focuses on inclusion, understanding, and accessibility.


🧠 Overall Summary (Modules 13–15)

Across these modules:

  • 🦶 Athlete’s Foot → simple fungal infection (skin level)
  • ❤️ AFib → serious heart rhythm disorder
  • 🧠 Autism → lifelong neurodevelopmental difference

Together they show how health conditions can affect:

  • Skin (infection)
  • Heart (electrical rhythm)
  • Brain development (neurodiversity)
