Diaphragmatic hernia is a defect or hole in the diaphragm that allows the abdominal contents to move into the chest cavity. Treatment is usually surgical. Types
Congenital diaphragmatic hernia
Morgagnis hernia
Bochdalek hernia
Hiatal hernia
Iatrogenic diaphragmatic hernia
Traumatic diaphragmatic hernia

Signs and symptoms
A scaphoid abdomen (sucked inwards) may be the presenting symptom in a newborn. Diagnosis
Diagnosis can be made by either CT or X-ray. Treatment
Treatment for a diaphragmatic hernia usually involves surgery, with acute injuries often repaired with monofilament permanent sutures. Other animals
Peritoneopericardial diaphragmatic hernia is a type of hernia more common in other mammals. This is usually treated with surgery. References

Cerebral atrophy is a common feature of many of the diseases that affect the brain. Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them. Brain atrophy can be classified into two main categories: generalized and focal atrophy. Generalized atrophy occurs across the entire brain whereas focal atrophy affects cells in a specific location. If the cerebral hemispheres (the two lobes of the brain that form the cerebrum) are affected, conscious thought and voluntary processes may be impaired. Some degree of cerebral shrinkage occurs naturally with the dynamic process of aging. The human brain completes growth and attains its full maturity at 25 years of age. Structural changes continue during adulthood as brain shrinkage commences after the age of 35, at a rate of 0.2% per year. The rate of decline is accelerated when individuals reach 70 years old. By the age of 90, the human brain will have experienced a 15% loss of its initial peak weight. Besides brain atrophy, aging has also been associated with cerebral microbleeds. Symptoms
Many diseases that cause cerebral atrophy are associated with dementia, seizures, and a group of language disorders called the aphasias. Dementia is characterized by a progressive impairment of memory and intellectual function that is severe enough to interfere with social and work skills.
