Aneurysm (brain)

brain aneurysm (AN-yoo-riz-um) is a bulge or ballooning in a blood vessel in the brain. It often looks like a berry hanging on a stem. A brain aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke).

An unruptured aneurysm usually causes no symptoms. A key symptom of a ruptured aneurysm is a sudden, severe headache.
Treatments for an unruptured aneurysm include medication to control blood pressure and procedures to prevent a future rup
Anaphylaxis

Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as peanuts or bee stings.

Symptoms include a skin rash, nausea, vomiting, difficulty breathing and shock.
If not treated right away, usually with adrenalin, it can result in unconsciousness or death.
Anaemia (iron deficiency)

As the name implies, iron deficiency anemia is due to insufficient iron. Without enough iron, your body can't produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath.

Iron deficiency often causes low blood cell levels (anaemia) and can delay the development of unborn babies. Treatment includes iron supplements and a focus on any underlying causes.
Alzheimer's disease

Alzheimer's disease is a progressive disorder that causes brain cells to waste away (degenerate) and die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that disrupts a person's ability to function independently.

Brain cell connections and the cells themselves degenerate and die, eventually destroying memory and other important mental functions.
Memory loss and confusion are the main symptoms.
No cure exists, but medication and management strategies may temporarily improve symptoms.
Allergies
Allergies
Allergies. An allergy is an immune system response to a foreign substance that's not typically harmful to your body. These foreign substances are called allergens. They can include certain foods, pollen, or pet dander.
Alcoholism
A chronic disease characterised by uncontrolled drinking and preoccupation with alcohol.
Alcoholism is the inability to control drinking due to both a physical and emotional dependence on alcohol.
Symptoms include repeated alcohol consumption despite related legal and health issues. Those with alcoholism may begin each day with a drink, feel guilty about their drinking and have the desire to cut down on the amount of drinking.
Treatment involves counselling by a healthcare professional. A detoxification programme in a hospital or medical facility is an option for those who need additional assistance. Medications are available that reduce the desire to drink.
Addison's disease

Addison's disease, also known as primary adrenal insufficiency and hypocortisolism, is a long-term endocrine disorder in which the adrenal glands do not produce enough steroid hormones. Symptoms generally come on slowly and may include abdominal pain, weakness, and weight loss.

Symptoms tend to be non-specific and include fatigue, nausea, darkening of the skin and dizziness upon standing.
Treatment involves taking hormones to replace those not produced by the adrenal glands.
Acne
Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. Acne usually appears on your face, neck, chest, back and shoulders. Effective treatments are available, but acne can be persistent. The pimples and bumps heal slowly, and when one begins to go away, others seem to crop up.
