Extrapyramidal symptoms (EPS), also known as extrapyramidal side effects (EPSE), are drug-induced movement disorders that include acute and tardive symptoms. These symptoms include dystonia (continuous spasms and muscle contractions), akathisia (motor restlessness), parkinsonism (characteristic symptoms such as rigidity), bradykinesia (slowness of movement), tremor, and tardive dyskinesia (irregular, jerky movements). Antipsychotics are often discontinued due to inefficacy and intolerable side effects such as extrapyramidal symptoms.

Since it is difficult to measure extrapyramidal symptoms, rating scales are commonly used to assess the severity of movement disorders. The Simpson-Angus Scale (SAS), Barnes Akathisia Rating Scale (BARS), Abnormal Involuntary Movement Scale (AIMS), and Extrapyramidal Symptom Rating Scale (ESRS) are rating scales frequently used for such assessment and are not weighted for diagnostic purposes; these scales can help physicians weigh the benefit/expected benefit of a medication against the degree of distress which the side effects are causing the patient, aiding in the decision to maintain, reduce, or discontinue the causative medication/s.

The extrapyramidal system regulates posture and skeletal muscle tone. Extrapyramidal symptoms (also called extrapyramidal side effects) get their name because they are symptoms of disorders in this system.

Some persons are sexually aroused by urolagnia, which can include the drinking of their own or other people's urine.

Urophagia is the consumption of urine. Urine was used in several ancient cultures for various health, healing, and cosmetic purposes – practices which are still used by some today, though there is no health benefit to it. Another reason for urophagia is in attempting survival if no other potable fluid is available, although numerous credible sources (including the US Army Field Manual) advise against it. Also, some people consume urine as a sexual activity.

Space adaptation syndrome (SAS) or space sickness is a condition experienced by around half of space travelers during adaptation to weightlessness. It is related to motion sickness, as the vestibular system adapts to weightlessness.

Space motion sickness is caused by changes in g-forces, which affect spatial orientation in humans. According to "Science Daily", "Gravity plays a major role in our spatial orientation. Changes in gravitational forces, such as the transition to weightlessness during a space voyage, influence our spatial orientation and require adaptation by many of the physiological processes in which our balance system plays a part. As long as this adaptation is incomplete, this can be coupled to motion sickness (nausea), visual illusions and disorientation."

Modern motion-sickness medications can counter space sickness but are rarely used because it is considered better to allow space travelers to adapt naturally over the first day or two than to suffer the drowsiness and other side effects of medication. However, transdermal dimenhydrinate anti-nausea patches are typically used whenever space suits are worn because vomiting into a space suit could be fatal, as it could obscure vision or block airflow. Space suits are generally worn during launch and landing by NASA crew members and always for extra-vehicular activities (EVAs). EVAs are consequently not usually scheduled for the first days of a mission to allow the crew to adapt, and transdermal dimenhydrinate patches are typically used as an additional backup measure.

Common symptoms include pain, intense tears, eyelid twitching, discomfort from bright light, and constricted pupils.

Canine subvalvular aortic stenosis (SAS) is an abnormal, congenital heart murmur caused by subaortic stenosis (SAS). There is a high incidence of this condition among Rottweiler dogs.

There is very good evidence that it is heritable, passed on from generation to generation genetically. This genetic trait is what is called polygenic, so that the inheritance is complex. An animal might have the genes for SAS, yet have no actual sign of SAS. Also, an animal might have signs of subaortic stenosis, and yet offspring with signs of SAS may not be seen for a couple of generations. Any animal that has subaortic stenosis should not be bred, because they can definitely pass the defect on to future offspring. There is some controversy as to whether the parents of an animal with SAS should be bred again.

Heart murmurs are graded on a scale of 1 to 6, with one being very mild and six being very serious, with some animals dying before they reach this high stage due to a sudden leap in the grade or through long-term slowing down. Murmurs can exist due to a large number of heart problems (infection, trauma, anemia, etc.; some are innocent, with no cardiac pathology. Tests such as chest X-rays, echocardiography, and electrocardiography can be performed to evaluate the severity of the situation

The condition is usually detected during puppy visits to the veterinarian by hearing a heart murmur during physical examination. A heart murmur is the abnormal sound of blood rushing through one of the heart valves. Instead of just the heartbeat, a whistle of blood flow through a narrowed opening is heard. The puppy will most likely appear normal in all other respects. There is a possibility that the murmur may come and go, or it may develop slowly; this can be determined by frequent checks of a puppy's heart during its first few months. The chance for long-term survival of SAS is low.

Puppies and dogs diagnosed with subaortic stenosis can suffer from heart failure and sudden death. If a dog with SAS develops heart failure, medications can be prescribed to alleviate the clinical signs (sudden/strong lethargicism, continuous heavy panting, rise in temperature etc.)

The OFA has established a Congenital Heart Registry whose guidelines were established by veterinary cardiologists. A dog which auscultates normally at 12 months of age is considered to be free of congenital heart disease; upon confirmation of this, the OFA will issue a certificate.

Aortic stenosis in the Rottweiler appears to be true subvalvular aortic stenosis (SAS), similar to that in the Newfoundland dog, as opposed to the valvular form (seen more in boxer dogs) or the supravalvular form sometimes seen in people.
