Dementia
What is dementia?
Dementia is a loss of mental abilities that is severe enough to interfere with daily life and activities. These abilities include:
- Memory
- Language skills
- Visual perception (understanding what you see)
- Problem-solving
- Completing everyday tasks
- Attention and focus
While mild forgetfulness can be a normal part of aging, dementia is not a normal part of aging. It is a serious medical condition that affects independence and quality of life.
What are the types of dementia?
The most common forms are neurodegenerative disorders, in which brain cells gradually stop working or die. These include:
- Alzheimer’s disease – The most common cause. It involves abnormal protein build-ups (beta-amyloid plaques and tau tangles) and loss of connections between brain cells.
- Lewy body dementia – Causes both cognitive decline and movement symptoms due to abnormal protein deposits (Lewy bodies).
- Frontotemporal dementia – Affects the frontal and/or temporal lobes, leading to behavior, personality, or language changes.
- Vascular dementia – Results from reduced blood flow to the brain, often after strokes or due to atherosclerosis.
- Mixed dementia – A combination of two or more types (for example, Alzheimer’s and vascular dementia).
Other conditions that can cause dementia or dementia-like symptoms include:
- Creutzfeldt-Jakob disease
- Huntington’s disease
- Chronic traumatic encephalopathy (CTE)
- HIV-associated dementia
Who is at risk?
Risk factors include:
- Aging (strongest risk factor)
- Smoking
- High blood pressure
- Uncontrolled diabetes

- Family history of dementia
What are the symptoms?
Symptoms vary depending on the type and affected brain areas. Common signs include:
- Getting lost in familiar places
- Forgetting names of close family or friends
- Using unusual words for common objects
- Difficulty reasoning or solving problems
- Needing help with tasks once done independently
- Personality changes or loss of emotional control
Some types also affect balance and movement.
Dementia progresses from mild impairment to severe dependence on others for care.
How is dementia diagnosed?
Health care providers may use:
- Medical history
- Physical exam
- Memory and thinking tests
- Blood tests
- Brain imaging (CT or MRI scans)

Aphasia
What is aphasia?
Aphasia is a language disorder that makes it difficult to speak, understand speech, read, or write. It is not a disease, but a symptom of damage to the parts of the brain that control language.
The signs of aphasia depend on which area of the brain is affected. There are four main types:
- Expressive aphasia – You know what you want to say but have trouble saying or writing it.
- Receptive aphasia – You can hear or see words but have trouble understanding their meaning.
- Global aphasia – Severe loss of language abilities, affecting speaking, understanding, reading, and writing.
- Anomic aphasia – Difficulty finding the right words for people, places, or objects.
Some people improve on their own, but aphasia can also be long-term. While there is no cure, treatment can help improve communication skills.
What causes aphasia?
Aphasia happens due to brain damage, most commonly from:
- Stroke (most common cause)
- Brain tumor
- Brain infection or inflammation
- Traumatic brain injury
- Progressive neurologic diseases, such as dementia
Who is at risk?
Anyone can develop aphasia at any age. However, it is more common in middle-aged and older adults. It often appears suddenly after a stroke or injury, but may develop gradually with brain tumors or progressive diseases.
How is aphasia diagnosed?
Health care providers may:
- Test understanding of language and speech
- Check the ability to follow simple commands
- Order imaging tests such as MRI or CT scans
Speech-language pathologists perform specialized tests to evaluate speaking, reading, writing, and comprehension.
Treatment
Treatment usually begins as soon as possible and may include:
- One-on-one speech-language therapy
- Group therapy
- Computer-assisted therapy
- Communication strategies using gestures, pictures, or devices
Family involvement is important. Helpful strategies include:
- Using simple language
- Repeating key words
- Writing things down
- Including the person in conversations
Recovery depends on the cause, location, severity of brain injury, and the person’s overall health.
Can aphasia be prevented?
Prevention focuses on reducing stroke and brain injury risk:
- Follow heart-healthy habits
- Manage blood pressure and diabetes
- Wear helmets during sports
- Prevent falls
- Always wear a seatbelt

Brain Diseases
Your brain is the control center of your body. It manages your thoughts, memory, speech, movement, and emotions. It also regulates many vital functions such as breathing, heart rate, and digestion. The brain works together with the spinal cord and peripheral nerves to form the nervous system, sending signals throughout your body.
When the brain is healthy, it works efficiently and automatically. But brain diseases can interfere with how you think, move, speak, or carry out daily activities.
Some common brain diseases include:
- Brain tumors, which may press on surrounding tissue and affect brain function
- Degenerative nerve diseases, such as Alzheimer’s disease and Parkinson’s disease, which gradually damage nerve cells
- Encephalitis, inflammation of the brain that can cause weakness, vision problems, or paralysis
- Genetic brain disorders are caused by changes (mutations) in genes
- Stroke, which interrupts blood flow to the brain
- Traumatic brain injury (TBI), which can range from mild to severe
Symptoms vary widely depending on the condition and area of the brain affected. Some brain diseases cause permanent damage, while others can improve with treatment such as surgery, medications, or rehabilitation therapies (physical, occupational, or speech therapy).
Caregivers
A caregiver provides care to someone who needs help taking care of themselves. This may be a child, adult, or older person who has an injury, disability, or chronic illness such as Alzheimer’s disease or cancer.
Caregivers may be:
- Informal caregivers (family members or friends)
- Professional caregivers (paid health care workers)
Care may be given at home, in hospitals, or in other care facilities. Some caregivers assist from a distance.
Responsibilities may include:
- Helping with bathing, dressing, eating, or taking medicine
- Cooking and housekeeping
- Running errands
- Driving to appointments
- Providing emotional support
- Arranging medical care
- Making health and financial decisions
Caregiving can be meaningful and rewarding. But it can also be stressful and overwhelming. Many caregivers are balancing work, children, and other responsibilities.
Taking care of your own health is essential. When caregivers look after their physical and mental well-being, they are better able to care for others.

Creutzfeldt-Jakob Disease
Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive brain disorder. Symptoms typically begin around age 60 and worsen quickly.
Symptoms may include:
- Memory loss
- Personality and behavior changes
- Vision problems
- Poor coordination
- Dementia
CJD progresses rapidly to severe disability, coma, and death. Most people with CJD die within one year of symptom onset.
There are three main types:
- Sporadic CJD – Occurs without a known cause
- Hereditary CJD – Runs in families due to genetic mutations
- Acquired CJD – Results from exposure to infected tissue, usually during certain medical procedures
A related disease in cattle, bovine spongiform encephalopathy (BSE or “mad cow disease”), has been linked to a rare variant form of CJD in humans.

- Spinal muscular atrophy
Many degenerative nerve diseases are serious and may be life-threatening. Most have no cure, but treatments can help manage symptoms, relieve pain, and improve mobility.
Down Syndrome
What is Down syndrome?
Down syndrome is a genetic condition caused by having an extra copy of chromosome 21. It affects how the body and brain develop.
Each person with Down syndrome has unique strengths and challenges.
What causes Down syndrome?
Chromosomes contain genetic information. People with Down syndrome have an extra chromosome 21, a condition also known as trisomy 21.
It usually happens randomly during early fetal development and is not typically inherited. The risk increases with maternal age, especially in women age 35 and older.
Common features
People with Down syndrome often have:
- Mild to moderate intellectual disability
- Delayed development
- A flat facial profile
- Upward-slanting eyes
- A short neck

Health Fraud
Health fraud scams involve selling medicines, supplements, devices, foods, or cosmetics that have not been proven safe or effective. At best, these products don’t work. At worst, they can be dangerous. They may also waste money and delay proper medical treatment.
Some possible dangers of scam products include:
- Being contaminated due to poor manufacturing practices
- Containing harmful ingredients not listed on the label
- Causing dangerous interactions with prescription medicines
- Leading to serious or life-threatening injuries
Fraudulent health products often claim to help with:
- Weight loss
- Memory improvement
- Sexual performance
- Joint pain
- Serious conditions such as cancer, diabetes, heart disease, HIV, or Alzheimer’s disease
Warning signs of health fraud
Be cautious of products that:
- Use testimonials from “real patients” or actors posing as doctors
- Claim to cure or treat many unrelated diseases
- Promote conspiracy theories (e.g., “hidden cure”)
- Use phrases such as:
- “Miracle cure”
- “Ancient remedy”
- “Quick fix”
- “Secret ingredient”
- “No-risk money-back guarantee”
- Use scientific-sounding but meaningless terms
- Claim endorsement by prestigious awards like a “Nobel Prize”
If something sounds too good to be true, it probably is.
Always talk to your health care provider before trying any unproven treatment, especially if you take prescription medicines.

Prevention
Prevent malnutrition by eating a balanced diet with a variety of foods and seeking medical advice if experiencing unexplained weight loss or growth concerns.
Metabolic Disorders
Metabolism is the process your body uses to convert food into energy. After you eat, your digestive system breaks down proteins, carbohydrates, and fats into sugars and acids. Your body uses this fuel right away or stores it in the liver, muscles, and fat tissue for later use.
A metabolic disorder happens when abnormal chemical reactions disrupt this process. As a result, your body may produce too much or too little of certain substances needed for good health.
Types of metabolic disorders
Metabolic disorders can affect different systems, including:
- Disorders of amino acid breakdown
- Carbohydrate metabolism disorders
- Lipid (fat) metabolism disorders
- Mitochondrial diseases (affecting energy production in cells)
Some metabolic disorders are inherited (genetic). Others develop when organs such as the liver or pancreas do not function properly.
An example of a metabolic disorder is Diabetes, which affects how the body processes blood sugar.
Treatment depends on the specific disorder and may include dietary changes, medicines, enzyme replacement, or other targeted therapies.

Mild Cognitive Impairment (MCI)
Some memory changes can be a normal part of aging. However, when memory problems are more noticeable than expected for a person’s age—but daily activities are still manageable—the condition may be mild cognitive impairment (MCI).
People with MCI can usually care for themselves and maintain independence.
Common symptoms
- Frequently losing items
- Forgetting appointments or events
- Trouble finding the right words
- More noticeable forgetfulness than peers
Memory problems can also result from medicines, depression, vitamin deficiencies, or conditions affecting blood flow to the brain. Some causes are treatable or reversible.
MCI may increase the risk of developing Alzheimer’s disease, but not everyone with MCI progresses to dementia.
Diagnosis
Your health care provider may:
- Conduct memory and thinking tests
- Review medications and medical history
- Refer you to a specialist if needed
There is currently no proven medication to cure MCI, but regular monitoring (every 6 to 12 months) is important.

Muscle Disorders
Muscles allow your body to move and perform essential functions such as breathing and maintaining posture. Muscle disorders can interfere with these abilities and may cause weakness, pain, stiffness, or paralysis.
Causes of muscle disorders
- Injury or overuse (sprains, strains, tendinitis)
- Genetic conditions such as Muscular dystrophy
- Certain cancers
- Inflammatory conditions (myositis)
- Nerve diseases that affect muscles
- Infections
- Side effects of certain medicines
In some cases, the exact cause is unknown.
Treatment depends on the underlying cause and may include physical therapy, medications, lifestyle changes, or surgery.

Oxygen Therapy
What is oxygen?
Oxygen is a gas your body needs to function properly. Your cells use oxygen to make energy. Your lungs absorb oxygen from the air you breathe, and it travels through your bloodstream to your organs and tissues.
When blood oxygen levels are too low, you may feel short of breath, tired, or confused. Low oxygen levels can also damage organs over time. Oxygen therapy helps increase the amount of oxygen your body receives.
What is oxygen therapy?
Oxygen therapy (also called supplemental oxygen) provides extra oxygen through a prescription from your health care provider. It may be used in a hospital, care facility, or at home. Some people need it short-term, while others require long-term therapy.
Oxygen can be delivered using:
- Oxygen tanks (liquid or compressed gas)
- An oxygen concentrator (which pulls oxygen from the air)
- A nasal cannula (nose tube)
- A face mask or oxygen tent
Portable systems are available to help people stay active while receiving therapy.
Who may need oxygen therapy?
You may need oxygen therapy if you have conditions that lower blood oxygen levels, such as:
- Chronic obstructive pulmonary disease (COPD)
- Pneumonia
- COVID-19
- Severe asthma attacks
- Late-stage heart failure
- Cystic fibrosis
- Sleep apnea
Risks of oxygen therapy
Oxygen therapy is generally safe, but possible side effects include:
- Dry or bloody nose
- Headaches
- Fatigue
Oxygen increases fire risk. Never smoke or use open flames near oxygen. Oxygen tanks should be secured upright to prevent injury.
What is hyperbaric oxygen therapy (HBOT)?
Hyperbaric oxygen therapy (HBOT) involves breathing oxygen inside a pressurized chamber. This allows the lungs to absorb more oxygen than at normal air pressure.
HBOT is used for:
- Serious wounds and burns
- Infections
- Air or gas embolisms
- Decompression sickness
- Carbon monoxide poisoning
Some centers claim HBOT treats conditions like Alzheimer’s disease, autism, or cancer. The U.S. Food and Drug Administration (FDA) has not approved HBOT for these uses. Always consult your provider before treatment.

Paget’s Disease of Bone
What is Paget’s disease of bone?
Paget’s disease of bone is a chronic disorder that disrupts normal bone remodeling. In healthy bone, tissue is broken down and rebuilt in a balanced way. In Paget’s disease, bones break down and regrow too quickly, making them larger, weaker, and misshapen. The disease usually affects one or a few bones.
Causes and risk factors
The exact cause is unknown. Both genetic and environmental factors may play a role. It is more common in:
- Older adults
- People of northern European descent
- Those with a family history of the disease
Symptoms
Many people have no symptoms. When symptoms occur, they may include:
- Bone pain
- Headaches or hearing loss (if the skull is affected)
- Bowing of limbs
- Enlarged head
- Hip pain
- Curvature of the spine
Possible complications
- Arthritis
- Heart failure (in severe cases)
- Kidney stones
- Nerve damage
- Rarely, bone cancer (osteosarcoma)
Diagnosis
Diagnosis may involve:
- Medical history and physical exam
- X-rays
- Alkaline phosphatase blood test
- Bone scan
Treatment
Treatment aims to reduce symptoms and prevent complications:
- Bisphosphonate medications
- Pain relievers
- Surgery (for fractures, severe arthritis, or nerve compression)
Adequate calcium and vitamin D intake and safe exercise can help maintain bone health.

Parkinson’s Disease
Parkinson’s disease is a progressive movement disorder. It occurs when nerve cells in the brain do not produce enough dopamine, a chemical that helps control movement.
Symptoms
- Tremor (shaking), often starting on one side
- Muscle stiffness
- Slowness of movement
- Poor balance and coordination
As the disease progresses, people may have difficulty walking, speaking, swallowing, or performing daily tasks. Depression and sleep problems are also common.
Diagnosis and treatment
There is no single test for Parkinson’s disease. Doctors use medical history and neurological exams to diagnose it.
There is no cure, but treatments include:

Stem Cells
Stem cells are unique cells that can develop into many different types of cells in the body. They help repair and maintain tissues.
Two main types are:
- Embryonic stem cells
- Adult stem cells
Stem cells can:
- Divide and renew for long periods
- Remain unspecialized
- Develop into specialized cells (muscle, blood, brain cells, etc.)
Research on stem cells may lead to treatments for conditions such as Parkinson’s disease, Alzheimer’s disease, spinal cord injuries, heart disease, diabetes, and arthritis.

Benefits
- Access to care from home
- Access to specialists
- Support for chronic disease management
- Lower costs in some cases
- Better communication and coordination
Limitations
- Technology problems
- Limited physical examination
- Insurance coverage may vary
- Follow-up coordination may be needed
Types of care available
Telehealth may be used for:
- Wellness visits
- Prescription refills
- Dermatology
- Eye exams

Urinary Incontinence
What is urinary incontinence (UI)?
Urinary incontinence (UI) is the loss of bladder control, meaning you may leak urine when you don’t want to. It is a common condition and can range from mild leakage to a problem that significantly affects daily life. The good news is that many types of UI can improve with proper treatment.
What are the types of urinary incontinence?
There are several types of UI, each with different causes and symptoms:
- Stress incontinence – Leakage happens when pressure is placed on the bladder, such as during coughing, sneezing, laughing, lifting, or exercise. It is often caused by weak pelvic floor muscles or changes in bladder position.
- Urge incontinence – You feel a sudden, strong need to urinate and may leak before reaching the toilet. It is commonly linked to overactive bladder. It may also be related to infections or neurological conditions such as Multiple sclerosis or spinal cord injuries.
- Overflow incontinence – The bladder does not empty completely, causing frequent or constant dribbling. It is more common in men and may be linked to diabetes, tumors, kidney stones, or certain medicines.
- Functional incontinence – Physical or mental conditions prevent reaching the toilet in time. For example, someone with arthritis may struggle with clothing fasteners, or a person with Alzheimer’s disease may not recognize the need to use the bathroom.
- Mixed incontinence – A combination of stress and urge incontinence.
- Transient incontinence – Temporary leakage caused by a short-term issue such as an infection or new medication.
- Bedwetting (nocturnal enuresis) – Urine leakage during sleep. It is common in young children but can also occur in adults. Adult causes may include medicines, caffeine, alcohol, urinary tract infections, kidney stones, enlarged prostate (BPH), or sleep apnea.
Who is at risk for urinary incontinence?
Adults are at higher risk if they:
- Are female, especially after pregnancy, childbirth, or menopause
- Are older (muscles weaken with age)
- Have prostate problems (in men)
- Have diabetes, obesity, or chronic constipation
- Smoke
- Have birth defects affecting the urinary tract
Children are more likely to experience bedwetting if they are younger, male, or have a family history of bedwetting.
How is urinary incontinence diagnosed?
Your health care provider may:
- Take a medical history and ask about symptoms
- Request a bladder diary (tracking fluids and urination)
- Perform a physical exam (including pelvic or rectal exam)
- Order urine or blood tests
- Conduct bladder function tests
- Use imaging tests
What are the treatments for urinary incontinence?
Treatment depends on the type and cause. Often, a combination of treatments works best.
Self-care treatments
- Lifestyle changes, such as:
- Drinking fluids at appropriate times
- Staying physically active
- Maintaining a healthy weight
- Avoiding constipation
- Quitting smoking
- Bladder training – Following a timed schedule for bathroom visits and gradually increasing the time between trips.
- Pelvic floor exercises (Kegels) – Strengthening muscles that control urine flow.
Other treatment options
- Medicines to relax bladder muscles, reduce urgency, or (in men) shrink the prostate
- Medical devices, such as:
- A catheter
- Vaginal support devices for women
- Bulking agents injected to help close the bladder opening
- Electrical nerve stimulation to improve bladder control
- Surgery, such as a sling procedure to support the bladder
If urinary incontinence is affecting your quality of life, talk to your health care provider. Many people improve significantly with treatment.
