It is considered the most common type of dementia and can be initially managed pharmacologically. The most common drugs are donepezil, rivastigmine and galantamine.

Amyotrophic lateral sclerosis or motor neuron disease is a progressive condition that affects the nervous system. It usually presents with weakness in the limbs, later spreading to the rest of the body. The speech, gait and cognitive performance will also get affected in time. Breathing and eating problems are some of the most severe complications. Treatment slows down the progression of the damage. 

Asthma is a disorder of the airways. It is characterised by alveolar hyper-reactivity and mucus hyper-secretion. As a result, the airways become narrow. Narrow airways result in breathing difficulties, wheezing and coughing. These phenomena together with breathlessness are the cardinal symptoms of asthma. As a condition, it can be triggered by a variety of situations. Asthma exacerbations are prevented and treated with inhalatory medication.

Brain tumor is a benign or malignant condition that is characterised by abnormal collection of brain cells in the brain. According to its type, it can be invasive or non-invasive. It can be primary or secondary, the latter being usually malignant. However, even benign tumors can be dangerous by compressing several brain structures.

Breast cancer is the second most prevalent form of cancer in women, after skin cancer. It refers to the cancer formed in the cells of the breast and it can have a very atypical presentation.

Screening tests such as Pap test, can identify this type of cancer in early stages. Vaccination is also a form of prevention.

Myalgic encephalomyelitis/chronic fatigue syndrome is a condition that bears great amounts of disability. It affects people for a period of time that may range from months to years and is characterized by extreme post-exertional malaise. People affected by it suffer from extreme fatigue but may look completely healthy. It is of unknown cause and difficult to diagnose.

If present, management consists in prevention of lung infections and management of the complications.  

Diabetes type 1 is a chronic metabolic disorder that results from complete lack of endogenous insulin. What causes lack of endogenous insulin is the auto-digestion of the beta-cells of the pancreas. As a result, very high levels of blood sugar develop leading to serious metabolic complications. Once developed, diabetes type 1 requires lifelong treatment with exogenous insulin, together with lifestyle modifications. 

Diabetes mellitus type 2 results from abnormally high blood glucose levels, leading to insulin resistance. It is a metabolic disorder that usually presents with polyuria, polydipsia and polyphagia. In severely high blood glucose levels, individuals might be diagnosed with hyperosmolar syndrome, a possibly lethal condition.

Emphysema is a lung condition and the result of damage in the alveoli. The hallmark of emphysema is dyspnea due to decreased lugg surface and therefore lower oxygen exchange capacity. Most commonly, emphysema coexists with chronic bronchitis in the context of chronic obstructive pulmonary disease. Smoking is the most important risk factor for both.

Endometriosis is a painful disorder that results from abnormal uterine tissue growth outside the uterus. Dysmenorrhea, dyspareunia, menorrhagia and infertility might be some of the symptoms endometriosis presents with.

Hyperthyroidism or overactive thyroid results in increased production of thyroid hormones from the thyroid gland. It can be primary or secondary and presents with signs of accelerated metabolism such as weight loss and tachycardia. Decreased tolerance to heat and irritability are also common. Radioactive iodine administration and medication to control heartbeat are recommended. 

Hypothyroidism results from low metabolic activity in the thyroid gland. Hormones produced by the thyroid gland are found in less concentrations or not at all, leading to serious complications. It can be asymptomatic or present with fatigue, weight gain, cold sensitivity, constipation or bradycardia. Some people may experience a goiter which is usually quite noticeable. Levothyroxine is the standard medication used to treat hypothyroidism and reverse its symptoms.

Treatment is chosen according to the size and location of the stone.

Lung cancer is a type of cancer that is primarily generated in the lungs. It is the number one cause of cancer deaths among other types of cancer in the US. Although lung cancer is strongly correlated to smoking, not being a smoker does not mean you can’t get lung cancer. Smoking, however, increases the risk significantly. Quitting smoking on time can significantly reduce the risk of developing lung cancer. 

Lyme disease is an infectious disease caused by the bacterium Borrelia. The cardinal sign of Borrelia infection is erythema migrans, an expanding area of skin erythema on the site of the infection. The bacterium is transmitted by a tick and except for rash, it can also cause fever. Treatment consists of oral or intravenous antibiotics. 

Macular degeneration is a progressive and degenerative eye condition that is considered the leading cause of blindness.

Joints that we use most during the day are also commonly affected. The cardinal symptoms of osteoarthritis are joint pain and stiffness. Swelling of the joints may also be present. Pain relieving medication and physiotherapy are the interventions preferred to manage osteoarthritis.

Osteoporosis is a condition that results in bone loss. Consecutively, the bone becomes weaker and more fragile, being able to break with a random fall or mild somatic stress. Sometimes osteoporosis can make a bone break by itself, a phenomenon called pathological fracture. Post-menopausal women are most likely to be affected.
