### diseases:

Adjustment disorder
* are less severe than other disorders.
* can manifest itself in many different forms
  - occur at any age
* is diseases
  - more likely to occur in cancer patients during critical times of the disease
  - very common in the United States

Alcohol intoxication
* are diseases.
* is equivalent to a drug overdose
  - often a contributor to violent behavior
  - the leading cause of traffic fatalities in the United States
* reduces visual sustained attention.

Alkalosis
* causes the arteries shrink so blood flow is restricted.
* decreases ionized Calcium.
* interferes with normal oxygen utilization by the brain.
  - hard to reverse once it occurs
  - less common than acidosis, and produces overexcitability of the nervous system
  - pathology
  - the opposite
* occurs less often than acidosis.
* tends to lower potassium levels in the serum as it shifts into the cells.

### diseases | alkalosis:

Metabolic alkalosis
* can be the result of diarrhea and vomiting.
* develops when the body loses too much acid.
* is alkalosis
  - caused by an excess of bicarbonate in blood

Respiratory alkalosis
* attenuates thromboxane- induced pulmonary hypertension.
* can occur when traveling to high altitudes, or with hyperventilation.
* is caused by abnormally low levels of carbon dioxide in the body
  - lower carbon dioxide levels
  - most common
* occurs due to hyperventilation.

Anal fissure
* are a fairly common disorder and occur more often in women
  - cracks or a split in the skin of the anal canal
  - diagnosed and evaluated by visual inspection of the anus and anal canal
  - splits in the anal mucosa immediately within the anal verge
  - the most common cause of rectal bleeding in infancy
* occur in the specialized tissue that lines the anus and anal canal, called anoderm.

### diseases:

Convulsion
* Keep the victim from nearby furniture and other objects to avoid injury.
* Most convulsions are brief, generalised and self limited, and are usually associated with fever
  - generalized and self-limited and are usually associated with fever
* are common during the early phase, particularly as the temperature rises
  - in infants but rare in older children
  - frequent, especially in children
  - the most common type of generalized seizures
  - uncontrolled body movements set off by an electrical malfunction of the brain
  - very frightening to watch for parents or siblings
* begin and death occurs
  - in the face
* begins at three months of age.
* can affect anybody at anytime
  - be severe enough to break bones
  - disturbances
  - trouble
* lead to lactic acidosis , hyperthermia and rhabdomyolysis.
* mark the onset of the disease, followed by dementia, spasticity and monoclonus.
* occur more frequently and each time their effects are felt more widely
  - often with the head, neck, back, and limbs rigidly extended
* often like tetanus, with lockjaw.
* usually involve the entire body.

### diseases | convulsion:

Epileptic seizure
* Most epileptic seizures are more likely to occur during sleep or when the individual is drowsy.
* are abnormal synchronous electrical discharges from specific neuron populations
  - part of epilepsy
  - the main neurological manifestations
* begin when one or more unstable neurons fire in an uncontrollable manner.
* can happen when a person is sleeping too.
* happen when neighboring neural cells all start firing in synchrony.
* is convulsion
* occur because of a sudden and abnormal discharge of electricity in the brain.
