OUR HERO - 11/20/1996 - 4/30/2004 Dylan Samuel Freeman Welcome To My Home Page!!!!! My name is Dylan was 7 years old. He was diagnosed with Alexander's Disease at age 4. The purpose of his web site is to help educate as many people as possible about this rare known disease and hopefully raise funds for research, for a treatment or cure. Maybe the research can't help Dylan. but please continue to donate, so Dylan's friends can be saved Dylan Samuel Freeman November 20th 1996 April 30th 2004 Everyone who meets him out on the town calls him HOLLYWOOD; since he insists on wearing his sunglasses to protect his Beautiful Blue Eyes. Everyone he meets falls in love with him at first sight. He is so polite with his "Hi's, Pleases, and Thank you's". He never wants to see anyone upset and he tries to keep everyone around him happy. His beautiful smile will win your heart the minute you lay eyes on him. Dylan Samuel Freeman, son of Sam and Kathy Freeman, was born on November 20th, 1996 in Brandon, Fl. At the age of 18 months, we noticed that he was having trouble with his balance, but he finally learned to walk at age 2. His doctor mentioned the possibility of mild Cerebral Palsy and said he would probably grow out of it. As it became more noticeable in his speech, we took him to another Neurologist in January 2001 at age 4. He had an MRI done and the doctor dianosed Alexander Disease and advised us to get a second opinion, since this was something that he had only read about at Harvard, but had never seen before.

Chronic Fatigue Syndrome And The Alexander Technique
How this centuryold method of releasing harmful stress may be of benefit to a patient with this disease.
http://www.alexandertechnique.com/articles/chronicfatigue

Extractions: Chronic Fatigue Syndrome and the Alexander Technique by Martin Finnegan What exactly is Chronic Fatigue Syndrome?* Sometimes referred to as ME or Myalgic Encephalomyelitis, it is a term that describes a chronic, debilitating disorder that affects the immune and central nervous system. Typical of its symptoms are a profound fatigue, totally out of proportion to a person's physical activity and independent of mood, plus a range of other symptoms that can affect any organ of the body. The causes of CFS are unknown. Indeed there appear to be any number of apparent causes and in many cases the onset seems to be linked to a stress to the immune system such as an acute infection, especially viral in nature. After the stress or virus has run its course the symptoms do not abate as you would expect but set in, becoming chronic and are often associated with profound fatigue and feelings of general malaise. Western medicine advocates rest, counseling, adjusting lifestyle and support as the best approach to treating CFS and this is all good advice. The problem, it seems to me is one of perception. The orthodox point of view perceives CFS as a thing. It is my opinion that CFS is not a thing at all, which is the reason that no cause and no diagnosis can be found. It is a process. A process of a human system running down, in a variety of ways, to such a point that it can't function properly anymore. In my own experience of CFS, it was exactly that and the solution was not to attempt to 'fix' a part of my body but to address the whole of 'me' and my life, in all its various aspects - physical, mental, emotional and spiritual. And the new model that I followed worked.

http://www.dylanfreeman.20m.com/about.html

Extractions: Alexanders disease belongs to a group of progressive neurological disorders in which the destruction of white matter in the brain is accompanied by the formation of fibrous, eosinophilic deposits known as Rosenthal fibers. The majority of cases of Alexanders are sporadic; that is, without a known family history of the disorder. There are, however, a number of families with more than one affected child. Alexanders disease begins in infancy, affects mostly males, and results in retarded development and dementia. It is quickly progressive and is the rarest of the identified leukodystrophies. The onset of the infantile form of Alexanders disease is usually around six months, but may occur between and 24 months of age. Children who develop Alexanders in infancy generally do not survive past the age of 5 or 6 years. Physical and mental development is retarded, and there is progressive enlargement of the brain and head, increasing spasticity, and seizures in some cases. Histologically, demyelination of both sensory and motor fiber tracts is found. In addition, the eosinophilic Rosenthal fibers are found evenly distributed throughout the brain near blood vessels, and on the surface of the brain. The demyelinated areas do not correspond to the distribution of the Rosenthal fibers. Alexanders disease is thought to be an autosomal recessive disorder which can affect both males and females. The metabolic error is unknown, and the demyelination and fiber formation seem to be otherwise unrelated parallel expressions of the disorder. It is the degeneration of the astrocytic glial cells which seems to lead to demyelination. An exact diagnosis may not be possible without study of postmortem tissues or brain or nerve biopsy.

Extractions: DEGENERATIVE DISEASES Imaging of degenerative disorders with CT has generally been disappointing, and attempts have been made to apply MR to this area with hopes of demonstrating more specific findings. The key to the MR imaging of many of these disorders may rest in understanding the normal and pathologic distribution of iron in the brain. Iron is visualized as areas of hypointensity on T2-weighted and GRE imagescaused by local field inhomogeneity and magnetic susceptibility effects. Drayer and colleagues noted decreased signal in the globus pallidus, reticular substantia nigra, red nucleus, and dentate nucleus. These areas correlated closely with sites of preferential accumulation of ferric iron on Perls' stains in normal brains post mortem. This iron deposition becomes greater with increasing age, with iron stains first becoming positive at 6 months in the globus pallidum and at 3 to 7 years in the dentate nucleus. With advanced age (approximately the ninth decade), there may be enough iron deposition in the putamen to render it as hypointense as the globus pallidus. Iron may play a role in neurotransmitter metabolism, and several degenerative disorders have been reported to be associated with increased iron deposition in the brain. This has been described in Hallervorden-Spatz disease, Huntington's chorea, Parkinson's disease and multisystem atrophy variants, Alzheimer's disease, and multiple sclerosis.

Stewart Alexander, 20th century, English pathologist), rare dysmyelinogenetic leukodystrophy , of sporadic occurrence without a familial incidence. There are three clinical subgroups: infantile, juvenile and adult. In the most common infantile form macrocephaly is the hallmark together with developmental delay, spasticity and seizures. The average duration of the illness is usually about 3 years. The juvenile form is characterized by onset between 7 and 14 years, spasticity, bulbar symptoms and a duration of about 8 years. In the adult the form onset of symptoms is variable as is the clinical manifestation that may have an intermittent course and resemble multiple sclerosis. There is no biochemical test to confirm the diagnosis. The CT and MR appearance ( Fig.1 ) of Alexander's disease is that of involvement of the white matter, starting bilaterally first in the frontal lobes and subsequently involving the peritrigonal temporoparietal regions. MR shows prolonged T1 and T2 relaxation times.

http://www.myelin.org/diseasesinbrief.htm

Extractions: IN THIS SECTION An Overview Demyelinating Diseases In Brief Scope and Strategies Demyelinating diseases are those in which myelin is the primary target. They fall into two main groups: acquired diseases (i.e., multiple sclerosis) and hereditary neurodegenerative disorders (i.e., the leukodystrophies). Although their causes and etiologies are different, they have the same outcome: CNS demyelination. Without myelin, nerve impulses are slowed or stopped, leading to a constellation of neurological symptoms. Axons with normal myelin Demyelinated axons: Nerve impulse conduction slows or stops completely The most common of these is multiple sclerosis (MS), which usually manifests itself between the 20th and 50th years of life. Current estimates are that approximately 2.5 million people worldwide have MS, with between 250,000 and 350,000 cases in the United States, 50,000 cases in Canada, 130,000 cases in Germany, 85,000 cases in the United Kingdom, 75,000 cases in France, 50,000 cases in Italy, and 11,000 cases in Switzerland. MS attacks the white matter of the central nervous system (CNS). In its classic manifestation (90% of all cases), it is characterized by alternating relapsing/remitting phases with periods of remission growing shorter over time. Its symptoms include any combination of spastic paraparesis, unsteady gait, diplopia, and incontinence.

Extractions: Back to Main List Alexanders disease is the rarest of the identified leukodystrophies. The infantile form tends to appear between birth and two years, and most sufferers of this form do not survive past the age of 5 or 6. The destruction of the white matter in the brain is accompanied by the formation of fibrous, eosinophilic deposits. These are known as Rosenthal fibres. Alexanders tends to be sporadic, appearing in families with no known history of the disorder. It is progressive, affects mostly males, and leads to both physical and mental retardation and dementia. The brain and head become progressively larger, leading the increased spasticity and sometimes seizures. The myelin sheath of both the sensory and motor fibre tracts is affected in Alexander's disease. The Rosenthal fibres are found distributed near the blood vessels of the brain and on the brain's surface. The nerves affected by the disease's demyelination do not correspond with the distribution of the Rosenthal fibres, and these two effects seem to be otherswise unrelated expressions of the disorder. The exact metabolic error that causes Alexanders disease is unknown, but it is thought to be an autosomal recessive disorder, which may affect both males and females. The demyelination seems to be cause by the destruction of the astrocytic glial cells.
