Delirium is a common geriatric syndrome characterized by a triad of symptoms: confusion, falls, and incontinence. It is often caused by an underlying medical condition, such as infection, dehydration, or medication side effects.

Muscle weakness, poor balance, and vision problems are all common causes of falls in older adults. These factors can make it difficult for older adults to maintain their balance and stability, increasing their risk of falling.

Sedatives, antidepressants, and diuretics are all common medications that can lead to falls in older adults. These medications can cause dizziness, lightheadedness, and impaired balance, increasing the risk of falling.

Dementia is a common geriatric syndrome characterized by a progressive decline in cognitive function. It is often caused by an underlying medical condition, such as Alzheimer's disease, Parkinson's disease, or vascular dementia.

Alzheimer's disease is the most common type of dementia, accounting for approximately 60-80% of cases. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior.

Memory loss, difficulty with language, and problems with visuospatial skills are all common symptoms of Alzheimer's disease. These symptoms can interfere with a person's ability to perform everyday activities.

Age, family history, and head injury are all common risk factors for Alzheimer's disease. The risk of developing Alzheimer's disease increases with age, and people with a family history of the disease are more likely to develop it. Head injury is also a risk factor for Alzheimer's disease, although the risk is small.

Cholinesterase inhibitors, memantine, and antipsychotics are all common treatments for Alzheimer's disease. Cholinesterase inhibitors and memantine are used to improve cognitive function, while antipsychotics are used to manage behavioral symptoms.

Parkinson's disease is a common geriatric syndrome characterized by a progressive decline in motor function. It is caused by a loss of dopamine-producing neurons in the brain.

Tremor, rigidity, and bradykinesia are all common symptoms of Parkinson's disease. Tremor is a shaking of the hands, arms, legs, or head. Rigidity is a stiffness of the muscles. Bradykinesia is a slowness of movement.

Age, family history, and exposure to toxins are all common risk factors for Parkinson's disease. The risk of developing Parkinson's disease increases with age, and people with a family history of the disease are more likely to develop it. Exposure to toxins, such as pesticides and herbicides, has also been linked to an increased risk of Parkinson's disease.

Levodopa, dopamine agonists, and anticholinergics are all common treatments for Parkinson's disease. Levodopa is a dopamine precursor that is converted to dopamine in the brain. Dopamine agonists are drugs that mimic the effects of dopamine. Anticholinergics are drugs that block the effects of acetylcholine, a neurotransmitter that can worsen the symptoms of Parkinson's disease.

Frailty is a common geriatric syndrome characterized by a progressive decline in functional status. It is often caused by a combination of factors, including muscle weakness, poor balance, and cognitive impairment.

Weight loss, fatigue, and slowed gait are all common symptoms of frailty. These symptoms can interfere with a person's ability to perform everyday activities.

Age, chronic illness, and disability are all common risk factors for frailty. The risk of developing frailty increases with age, and people with chronic illnesses or disabilities are more likely to develop it.
