Different frame patterns especially useful when one eye is involved in a disease can be used to highlight signals from the rods, cones or process. Individual signals from the rods and cones can also be the timing of the onset of the response (latency) is a extracted. Delay is therefore an important sign in the diagnosis of a past attack of retrobulbar neuritis In a majority of cases, examination of the visual acuity with (Figs 10. This oc curs because of a cortical summation of the visual input from the two eyes. Various devices such as the synoptophore, Bagolini striated glasses, polarized projectors and binocu lar visual felds (tested with different coloured glasses in front of the two eyes) are used to assess if the two eyes are functioning together. Stereoacuity is a measure of the ability of the eye to detect horizontal disparity and is normally about 40 to 60 seconds of an arc.

To make this diagnosis, other causes of daytime sleepiness without sleep deprivation must be ruled out. This fear causes patients to avoid any new or social situations that might be potentially embarrassing, and to feel extremely inadequate about the ability to start and maintain any kind of relationship. Conversely, patients with schizoid personality disorder, while every bit as isolated as those with avoidant personality disorder, like it that way. They rarely come to psychiatric attention because their social isolation is ego-syntonic. Question 386 refers to a patient with obsessive-compulsive disorder (not obsessive-compulsive per sonality disorder). Question 387 refers to a delusional patient (in this case, the patient has paranoid delusions). Delusions are fixed false beliefs that by their very definition cannot be changed.

The most important thing for the doctor to say at this time is (A) "Do not worry, there are many effective medications for depression. The mother of a 3-year-old child tells you that although she instructs the child to sit still at the dinner table, the child cannot seem to do so for more than 10 minutes at a time. A normal 8-month-old child is brought to the pediatrician for his monthly well-baby examination. Her desire to sleep with her mother is a sign of regression, a defense mechanism that is common in normal children under stress. Because she continues to play well when away from her mother, this is not separation anxiety disorder. Children under the age of 6 years do not understand the finality of death and fully expect dead people to come back to life. That is why, although he has been told that his father has died, this child repeatedly asks for his father. While he has been severely stressed, he is neither simply refusing to believe the truth nor showing delayed development. While it is possible that this boy has an undiagnosed head injury, a normal reaction is more likely. The conception of death in a 7-year-old child is that others can die but that he cannot die. It is not until about age 9 that children begin to understand that they can also die. Children under age 6 expect that death is temporary and that people who die come back to life. The physician should reassure the mother that all children are different and that some crying is normal in an infant. Crying does not mean that the child falls into the category of "difficult" infant. This child is likely to show reactive attachment disorder after this prolonged separation from his mother. Although the orphanage is well kept, it is unlikely the child has been able to form a stable attachment to another caretaker because of the high number of staff changes. These reactions include depression, decreased responsiveness to adults, and deficits in the development of social and motor skills. Toilet training or the ability to spend most of the day away from the mother does not usually occur until age 3.
