Reduced interest in sex When to see a doctor Unfortunately, many people with anorexia don't want treatment, at least initially. Their desire to remain thin overrides concerns about their health. If you have a loved one you're worried about, urge her or him to talk to a doctor. If you're experiencing any of the problems listed above, or if you think you may have an eating disorder, get help.

Several neurodegenerative disorders also may present with parkinsonism and are sometimes referred to as "atypical parkinsonism" or "Parkinson plus" syndromes illnesses with parkinsonism plus some other features distinguishing them from PD. They include multiple system atrophyprogressive supranuclear palsycorticobasal degenerationand dementia with Lewy bodies DLB.

Some of these non-motor symptoms may be present at the time of diagnosis. Parkinsonian gait Four motor symptoms are considered cardinal in PD: A feature of tremor is pill-rolling, the tendency of the index finger and thumb to touch and perform together a circular movement.

Performance of sequential and simultaneous movement is impaired. It leads to particular difficulty in carrying out two independent motor activities at the same time and can be made worse by emotional stress or concurrent illnesses.

While most physicians may readily notice bradykinesia, formal assessment requires a patient to do repetitive movements with their fingers and feet. Postural instability is typical in the later stages of the disease, leading to impaired balance and frequent falls, [36] and secondarily to bone fracturesloss of confidence, and reduced mobility.

Freezing of gait brief arrests when the feet seem to get stuck to the floor, especially on turning or changing directiona slurred monotonous quiet voice, mask-like facial expression, and handwriting that gets smaller and smaller are other common signs.

This includes disorders of cognition, mood, behavior, and thought. The dopamine dysregulation syndrome — with wanting of medication leading to overusage — is a rare complication of levodopa use Giovannoni, et al. Behavior and mood alterations are more common in PD without cognitive impairment than in the general population, and are usually present in PD with dementia.

The most frequent mood difficulties are depressionapathyand anxiety. Punding in which complicated repetitive aimless stereotyped behaviors occur for many hours is another disturbance caused by anti-Parkinson medication.

Auditory hallucinations are uncommon in PD, and are rarely described as voices. It is now believed that psychosis is an integral part of the disease.

A psychosis with delusions and associated delirium is a recognized complication of anti-Parkinson drug treatment and may also be caused by urinary tract infections as frequently occurs in the fragile elderlybut drugs and infection are not the only factors, and underlying brain pathology or changes in neurotransmitters or their receptors e.

Sleep problems are a feature of the disease and can be worsened by medications. Never having smoked cigarettes, and never drinking caffeinated beverages, are also associated with small increases in risk of developing PD.

It has been suggested that some cases of PD may be caused by lysosome dysfunctions that reduce the ability of cells to break down alpha-synuclein. The brown colour is positive immunohistochemistry staining for alpha-synuclein. This loss of neurons is accompanied by the death of astrocytes star-shaped glial cells and a significant increase in the number of microglia another type of glial cell in the substantia nigra.

These are known as the motoroculo-motorassociativelimbic and orbitofrontal circuits, with names indicating the main projection area of each circuit. When a decision is made to perform a particular action, inhibition is reduced for the required motor system, thereby releasing it for activation.

Dopamine acts to facilitate this release of inhibition, so high levels of dopamine function tend to promote motor activity, while low levels of dopamine function, such as occur in PD, demand greater exertions of effort for any given movement. Thus, the net effect of dopamine depletion is to produce hypokinesiaan overall reduction in motor output.

This insoluble protein accumulates inside neurones forming inclusions called Lewy bodies. As the disease progresses, Lewy bodies develop in the substantia nigra, areas of the midbrain and basal forebrain and, finally, the neocortex.

Other forms of alpha-synuclein e. It may be related to oxidative stressprotein aggregation and neuronal death, but the mechanisms are not fully understood.The two most common eating disorders are Anorexia Nervosa and Bulimia Nervosa. In this essay, I will compare and contrast these two disorders.

This essay will also assess the symptoms, causes, health affects and the most prevalent characteristics of people diagnosed with these two eating disorders. Parkinson's disease (PD) is a long-term degenerative disorder of the central nervous system that mainly affects the motor system.

The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking.

Thinking and behavioral problems may also occur. Dementia becomes common in the advanced stages of the. Harrington BC, et al.
