  • In this slide show we will discuss the disorder prosopagnosia and how it affects your behavior as well as your nervous system. Prosopagnosia is disorder that causes your face to go blind. It is more prevalent with kids with Autism and Asperger syndrome, it is also believed to be inherited since it appears to be present in more than one individual in some families. The slide show will also discuss how and if the brain is affected by this disorder how will it react to it, and do this disorder affect your five senses. If the brain is affected by prosopagnosia the slide show will also talk about the regions that it has affected. Last but not least we will talk about if there are any theory for this disorder, and how someone acts with this disorder and how he or she cope with this disorder.
  • Oliver Sacks was born with prospagnosia. The disorder affects the patients ability to recognize faces but does not impair the ability to recognize other objects. Sacks never realized that he had prospagnosia until later in his life when he confused one brother with another. Upon talking to other family members he found that several of them had similar trouble with facial recognition.
  • The understanding of recognition, face recognition specifically has not always been understood. Like many questions regarding the brain and its mental function, it wasn’t until the late 1800 when autopsy’s and other studies of the brain became more prevalent that the underlying cause for diseases such as prosopagnosia would be discovered. Many neurologist have studied the cause of prosopagnosia over the past few decades. There are several commonalities amongst the studies. The main focal point for damage in the brain for individuals with prosopagnosia is lesions found on the fusiform gyrus. The fusiform gyrus stretches from the occipital cortex to the prefrontal area of the brain. It is believed that the severity of the disease can be understood in knowing the location and size of the lesion. The further away the lesion is from the face recognition area location of the gyrus, the more mild the case symptoms present themselves.
  • Having Prosopagnosia can have an adverse effect on one’s life in the social aspect which can lead to health problems such as depression. There are few who have found ways to cope and have a fairly normal life. However most have a hard time interacting socially with friends, relatives, and personal relationships. Those effected by this this ailment tend to stay away from public interaction of any kind simply because they can not deal with what they perceive others think. This kind of anti social behavior can even lead to loss of career and ability to live a quality lifestyle of any kind leading to one or more social disorders ("Information About Prosopagnosia", 2011).
  • Most brain disorders or trauma rely on brain plasticity in order to compensate for effective mental or motor skills; one part or system of the brain may take over the functions of a defective or damaged one. But this does not seem to occur with Prosopagnosia, these conditions are usually life-long and do not lessen as one ages. Very few successful therapies have been developed for affected people and patients tend to undergo behavioral therapy to learn to make associations and develop clues to recognize people. Most individuals often learn to use ‘feature by feature’ recognition. As was the case with Oliver Sacks, he tended to recognize acquaintances by distinguishing facial features, and even stated that he better recognized characters rather than the real thing. Other patients recall using verbal encoding to remember where she sits objects or landmarks to familiarize locations. Ultimatley there are no underlying cures for Prosopagnosia, but understanding the condition and creating personal memory techniques can help individuals suffering form this disorder to navigate more easily through everyday life.
  • This is from a person that suffers with Prosopagnosia and their hope and dreams for the future, even though they suffer with this disease. Findingstrengthtostandagain was asked two question in the article; One was “When you have lost so much vision, how hard is it for you to cope? (Findingstrengthtostandagain  2011).” And the second question was “Since you have lost most of your visual memory and ability to recognize faces, do you still have dreams? (Findingstrengthtostandagain  2011).”It is very interesting to read in this article the answers to these two question asked of this author. His answers are short ones, to the first question, his answer is “yes, he would love to see more, and “yes” thoughts still fill his sleep, but there are no images”. From his article, he states these beautiful words; “Dreams are not always the images and pictures your imagination creates.  Sometimes a dream is what you hope for in the future.  I do have hope.  Regarding the night dreams people are referring to when asking this question, my imagination still fills my sleep with stories at night.  With prosopagnosia, these dreams are limited but still very realistic.  I no longer see pictures of people running.  I no longer see the cliff I am stepping off, but I still wake with a falling sensation.  Yet, I still have dreams that leave me uneasy in the morning or can cause tears to come in the night.  Like my waking hours no images fill my mind.  With closed eyes, I experience only darkness.  My dreams are remembered in a mind that no longer sees pictures (Findingstrengthtostandagain  2011).” “I do not need sight to have a vision.  I have enough words, memories and hope to always have dreams.  Yes, prosopagnosia and hemianopia have certainly altered the way I see and feel, but I always believe I have gained more and understand more now.  This outweighs all I have ever lost.  I love the vision and dreams that promise an exciting future (Findingstrengthtostandagain  2011).”After reading what this author has to say concerning his illness, can we each not see and feel in his words the “hopes and Dreams” of his life?
  • This representation displays that Prosopagnosia is a neurological disorder that is characterized by the inability to recognize faces… even a person’s own. This disorder is not related to memory dysfunction, memory loss, impaired vision, or learning disabilities; it is known to be the result of abnormalities such as brain damage, or impairment in the right fusiformgyrus. The fusiformgyrus is a fold in the brain that functions to coordinate the neural systems that controls our facial perception and memory. People who have suffered from a stroke, traumatic brain injury, or certain neurodegenerative diseases may possess Prosopagnosia (National Institute of Neurological Disorders and Stroke, 2007).This disorder cripples individuals socially and they must rely on other ways to identify individuals in their environment. They rely on the voices, clothing, or unique physical attributes – this method helps, but there is nothing like the ability to recognize the face of an individual. Being that this is a crippling disorder; when treating individuals with Prosopagnosia, a Physician must focus on helping the individual develop compensatory strategies (National Institute of Neurological Disorders and Stroke, 2007).The National Institute of Neurological Disorders and Stroke (NINDS) participate in research studies that are related to Prosopagnosia. This organization also participates in additional research through grants and major medical institutions. A vast amount of these conducted researches solely focuses on implementing new and improved ways to prevent, treat, and cure disorder like Prosopagnosia (National Institute of Neurological Disorders and Stroke, 2007).
