This guide will help you answer 3.1 Describe conditions affecting the elderly, to include: • dementia • Parkinson’s disease • stroke/Transient Ischaemic Attack (TIA)• arthritis • osteoporosis.

As people age, they can experience a range of health conditions. These may affect their physical or mental well-being. Understanding these conditions helps provide better care and support. In this guide, we provide an overview of dementia, Parkinson’s disease, strokes and Transient Ischaemic Attacks (TIAs), arthritis, and osteoporosis.

Dementia

Dementia is a term used to describe a range of symptoms caused by brain damage. It includes memory loss, confusion, and difficulty with daily tasks. It is not a normal part of ageing.

There are different types of dementia, including:

• Alzheimer’s disease: This is the most common cause of dementia. It happens when abnormal proteins build up in the brain, damaging brain cells. Common symptoms include memory problems and difficulty finding words.
• Vascular dementia: This occurs when reduced blood flow damages brain cells. It can follow a stroke or TIA. Symptoms may include difficulty making decisions, slowed thinking, and loss of concentration.
• Lewy body dementia: This is caused by the buildup of abnormal proteins called Lewy bodies. Symptoms include visual hallucinations, movement problems, and sleep disturbances.

Dementia progresses over time. Early signs may involve small memory lapses or confusion, but severe cases can result in complete dependence on others. There is no cure, but treatments and therapies, such as medication and brain activities, can help manage symptoms.

Parkinson’s Disease

Parkinson’s disease is a neurological condition that affects movement. It occurs when nerve cells in the brain stop producing dopamine. Dopamine helps transmit signals that control movement and coordination.

Key symptoms include:

• Tremors: Involuntary shaking, often starting in the hands or fingers.
• Stiff muscles: Muscles can become rigid, making movement painful or difficult.
• Slowness: Movements become slower, making simple tasks harder.

The condition may also cause non-movement symptoms, such as:

• Depression or anxiety
• Trouble sleeping
• Speech problems
• Loss of sense of smell

Over time, symptoms worsen, leading to greater difficulty with daily activities. Parkinson’s is progressive, meaning it gets worse, but it varies between individuals. While there is no cure, medications like levodopa can reduce symptoms. Physiotherapy can also help improve mobility and flexibility.

Stroke and Transient Ischaemic Attacks (TIAs)

A stroke happens when blood flow to the brain is reduced, causing brain cells to die. This can result from a blood clot blocking a blood vessel or bleeding in the brain. A TIA, sometimes called a “mini-stroke,” is a temporary blockage of blood flow and does not cause permanent damage.

Symptoms of both include:

• Sudden weakness, often on one side of the body
• Drooping face, usually on one side
• Difficulty speaking or understanding others
• Vision problems, such as blurred or double vision

The FAST test helps spot a stroke:

• Face: Check for drooping on one side of the face.
• Arms: See if the person can raise both arms equally.
• Speech: Listen for slurred or unclear speech.
• Time: Act quickly if any of these signs occur.

TIAs are warning signs of a future stroke. Both conditions need urgent medical attention. Treatments may involve medication, such as blood thinners, or surgery to improve blood flow.

After a stroke, recovery depends on the severity. Rehabilitation may include speech therapy, occupational therapy, and physiotherapy. The goal is to improve mobility, communication, and independence.

Arthritis

Arthritis is a condition that causes inflammation and pain in the joints. It is very common in older adults and can reduce mobility and quality of life.

Types of arthritis include:

• Osteoarthritis: This is the most common type, caused by wear and tear on joints. Over time, the cartilage that cushions the joints breaks down. Symptoms include stiffness, swelling, and pain, especially in weight-bearing joints like the knees, hips, and spine.
• Rheumatoid arthritis: This is an autoimmune condition where the body’s immune system attacks healthy joint tissue. It causes swelling, pain, and visible deformities. It can also affect other organs.

Arthritis can lead to difficulty with daily tasks such as dressing, cooking, or moving around. Treatments help manage symptoms but do not cure the condition. These may include:

• Pain relief medication
• Anti-inflammatory drugs
• Physiotherapy
• Joint replacement surgery for severe cases

Osteoporosis

Osteoporosis means “porous bones.” It weakens bones, making them fragile and more likely to break. It develops slowly and often goes unnoticed until a fracture occurs.

Bone density naturally reduces with age, but osteoporosis speeds up this process. Older adults, especially women after menopause, are at higher risk. Factors that increase the risk include:

• A family history of osteoporosis
• Poor diet with low calcium and vitamin D
• Lack of exercise
• Smoking or excessive alcohol consumption

The most common fractures occur in the hip, wrist, or spine. These injuries can lead to long recovery times, reduced independence, and further health problems.

Preventative steps include maintaining a healthy diet with sufficient calcium and vitamin D, regular weight-bearing exercises, and avoiding smoking or excessive alcohol. Medications may also be prescribed to strengthen bones and slow bone loss.

Final Thoughts

The elderly may face several challenging health conditions, including dementia, Parkinson’s disease, strokes, arthritis, and osteoporosis. Each has unique symptoms, effects, and treatments. Early detection and proper support improve an individual’s quality of life. By understanding these conditions fully, care workers can provide effective and compassionate care.
