I need some assistance with these assignment. whats eating gilbert grape based on the movie, for mental illness Thank you in advance for the help! In the movie, Arnie is faced with a very difficult life considering the tough situations that are affecting their familys life and the developmental disability that has made his life more of a burden to his brother who seems to be the only person in a position to care for the entire family. Developmental disorder is simply a term that is commonly used in the United States and Canada in an effort to bring to light disabilities that are life long. The disabilities that are described as being developmental are inclusive of all the mental and physical impairments that tend to be observed in children before they reach the age of 18 years. The development disability is usually as a consequence of trauma or even illness that is temporary during childhood. In the case of the movie Whats Eating Gilbert Grape, it can be said that the developmental disorder that seems to put on hold Arnies life is as a consequence of mental impairment. As it can be clearly seen in Arnie, the developmental disability makes it very difficult for the character to live an independent life because it reduces the capacity of an individual to have an independent living. it disables ones ability to have self direction and the inability of an individual to learn (Habib, 49).
