What is dementia?

Dementia is a general term for a group of conditions characterized by a decline in memory, thinking and reasoning. Dementia is not simply age-related forgetfulness. It is associated with other changes as well. It makes a person unable to perform their routine tasks. They find it difficult to focus, understand, concentrate and have a conversation besides other complaints. Dementia is associated with abnormal brain cell changes that may occur due to several conditions such as
- Alzheimer’s disease
- Vascular dementia
- Dementia with Lewy bodies
- Frontotemporal dementia
- Parkinson’s disease
- Huntington’s disease
- Human immunodeficiency virus (HIV)
- Traumatic brain injury
- Dementia due to medications
- Dementia due to alcohol and other substance abuse
What are the early signs of dementia?
The early signs of dementia may vary depending on the cause of dementia. Some of the early signs include
- A progressive decline in memory
- Inability to focus and concentrate
- Repeatedly asking the same questions
- Forgetting something they just read or heard
- Trouble staying organized
- Becoming overly anxious
- Finding it difficult to make and execute plans
- Forgetting names
- A lack of interest in the surroundings. The person avoids holding conversations or participating in activities.
- Inability to remember personal details such as phone number and home address.
- They may confuse people and relations. For example, they may confuse their wife with their mother.
- They forget names, but may recognize faces.
- They may exhibit loss of bowel and bladder control.
- Abnormal visual perceptions such as hallucinations (seeing things that are not there) and inability to detect movement or see the difference between colors.
- The person needs help for basic needs such as eating, drinking, sitting up and walking. Eventually, they may even forget how to smile or swallow their food properly.
- They often develop stiffness and joint deformities.
Can dementia be cured?
Most types of dementia, such as Alzheimer’s disease, involve irreversible changes in the brain, so they cannot be cured. Dementia due to certain reasons such as medications, vitamin deficiencies and alcohol use may be curable.
Although most types of dementia cannot be cured, they can be managed. The management of dementia involves a comprehensive approach involving the support of family and friends, psychological therapies, medications, diet and physical activity.
- Medications: Medicines for dementia include
- Cholinesterase inhibitors such as donepezil, rivastigmine and galantamine
- Memantine
- Antidepressants such as selective serotonin reuptake inhibitors (SSRIs)
- Medications to manage anxiety such as lorazepam and oxazepam
- Antipsychotic medications such as haloperidol, olanzapine and risperidone
- Medications to manage underlying health conditions such as diabetes and hypertension
- Therapies such as cognitive stimulation therapy (CST) and occupational therapy
- Relaxing rituals such as meditation, adequate sleep and music
- A healthy diet and regular exercise

Alzheimer's Disease
Alzheimer's disease is a common cause of dementia. Symptoms and warning signs of Alzheimer's disease include memory loss, difficulty performing familiar tasks, disorientation to time and place, misplacing things, and more. The biggest risk factor for Alzheimer's disease is increased age. Treatment for Alzheimer's is often targeted toward decreasing the symptoms and progression of the disease.benztropine
Benztropine is a medication used as an adjunct therapy for the treatment of all forms of Parkinson’s disease. Common side effects of benztropine include rapid heart rate (tachycardia), confusion, disorientation, depression, memory impairment, nervousness, visual hallucinations, worsening of psychotic symptoms, toxic psychosis, lethargy, numbness of fingers, absence of sweating (anhidrosis), high body temperature (hyperthermia), and others. Safety of use in pregnancy is not established, avoid use. Anticholinergic medications may suppress lactation and it is not known if it is excreted in breast milk, avoid use.Dementia Foods: Foods that May Lower Dementia Risk
What foods are associated with Alzheimer's disease and other forms of dementia? Cognitive function is predicated on good nutrition. Learn how vegetables, whole grains, and lean proteins like fish can lead to a healthier brain. Discover why foods that stave off heart disease are good for brain function.Dementia
Dementia is defined as a significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. There are several different types of dementia, including cortical, subcortical, progressive, primary, and secondary dementias. Other conditions and medication reactions can also cause dementia. Dementia is diagnosed based on a certain set of criteria. Treatment for dementia is generally focused on the symptoms of the disease.Bad Brain Health Habits
Good brain health depends on exercising regularly, eating well, and getting enough sleep. Learn how to develop good health habits to protect your brain against neurodegeneration, Alzheimer's disease, and other kinds of dementia.The Stages of Dementia: Alzheimer's Disease and Aging Brains
What are the symptoms of dementia? What causes dementia? Dementia includes many disorders, such as Lewy Body dementia, Alzheimer's disease, vascular dementia, and more. Learn the warning signs of dementia.What Is the Difference Between Dementia and Alzheimer's?
Dementia is a group of symptoms (syndrome) characterized by a decline in memory, thinking and reasoning. Although dementia is a cluster of symptoms, Alzheimer’s is a slowly progressive disorder of the brain that destroys memory and thinking skills.Down Syndrome
Get the facts on Down syndrome, a genetic disorder caused by an additional set of chromosomes in a developing fetus. Down syndrome signs and symptoms include distinctive facial features, growth retardation, and decreased mental function and IQ. Blood tests and ultrasound may be used to screen for Down syndrome but chromosome analysis of the fetus is needed to diagnose the condition. People with Down syndrome age more quickly and may develop Alzheimer's disease as young as age 40. Sometimes people are diagnosed with mosaic Down syndrome, in which case they have more than one type of chromosomal makeup.Early Warning Signs and Stages of Dementia
Dementia is a decline and or loss of behavior of mental abilities, loss of judgment, language, and reasoning. Early warning signs of dementia include misplacing items, difficulty planning or problem solving, poor work performance, difficulty doing familiar tasks, and withdrawal from social activities.
There are seven stages of dementia that range from stage 1, with no cognitive decline to stage 7, which is severe dementia.Ginkgo Biloba
Ginkgo biloba is a leaf extract used as a dietary supplement with recommended uses such as altitude sickness prevention, reduction of cardiovascular disease risk, cerebral vascular insufficiency, cognitive disorders, dementia, dizziness and vertigo, intermittent claudication, macular degeneration, glaucoma, memory loss, premenstrual syndrome (PMS), sexual dysfunction, and vasodilation. Common side effects of Ginkgo biloba include gastrointestinal upset, nausea, vomiting, constipation, diarrhea, headache, weakness, dizziness, vertigo (rare), restlessness, seizures, palpitations, and others.Reasons for Memory Loss and Dementia Risk
