1) Fill in the pertinent information with regard to Parkinson’s Disease:
Demographics (include any information on prevalence rates, age of onset, populations at risk): According to the text, Parkinson’s Disease is observed in 1% of the people over the age of 65. It seems safe to say that while this disease is a rare occurrence, people over the age of 65 are at a higher risk than other people.
Symptoms: Symptoms of Parkinson’s Disease include but are not limited to: muscular rigidity, slowness of movement, a resting tremor, and posture instability.
Underlying neurobiology: According to the text, there is a near-disappearance of nigrostriatal dopaminergic neurons. Of the surviving dopaminergic neurons there are lewy-bodies present.

(A thought disorder – disorganized, irrational thinking are some of the most important symptoms of Schizophrenia).
Negative Symptoms: flattened emotional responses, poverty of speech, lack of initiative/persistence, the inability to experience pleasure (referred to as anhedonia), as well as social withdrawal.
Cognitive Symptoms: difficulty in holding attention, low psychomotor speech, learning and memory deficits, poor abstract thinking, and poor problem solving.
Underlying neurobiology (dopamine hypothesis, brain abnormalities, prefrontal cortex)
Negative and cognitive symptoms are seen within many neurological disorders. These disorders typically are related to some type of brain damage to the frontal lobes. Positive symptoms are slightly different, they seem to involve excessive activity in a few neural circuits that include dopamine as a neurotransmitter, while negative and cognitive symptoms seem to be caused by or related to degenerative or developmental processes, of which impair normal functions of some of the regions within the brain.
The dopamine hypothesis essentially claims that that the positive symptoms of Schizophrenia are due to over-activity of DA

This is the fourth leading cause of disability. Bipolar disorder affects both men and women equally.
Description/Symptoms: Major affective disorders are mood disorders. There are two principle types of these disorders including, bipolar disorder and major depressive disorder.
Bipolar disorder involves altering states of depression and mania. Bipolar episodes (mania) can last for varying amounts of time ranging from a few days to a few months. These episodes typically take a few weeks to run their course. The episodes of depression that follow the episodes of mania typically last for an extended period of time, ranging up to three times as long as the manic episode.
Some symptoms of depression usually result in people feeling unworthy, guilty, and are at a much higher risk for suicide. 15.9% of people with MDD and 29.2% of people with bipolar disorder attempt to commit suicide. This essentially declares suicidal thoughts as a potential symptom.
Depressed people, lack energy, talk and/or move slowly, may display signs of lethargy, or may frequently pace restlessly/aimlessly, increased crying, lack of appetite, lack of sexual appetite, and may suffer from irregular sleep cycles. Physical symptoms may include constipation, and less saliva
By the time someone shows signs and symptoms of Parkinson 's, Dopamine production in the brain has been reduced by 60 to 80% and is fairly advanced. This results in the most recognizable sign of Parkinson 's disease, the resting tremor of the hand or hands. During deliberate movement, the resting tremor goes away, at first. At rest, the tremor will become exacerbated,
To begin Parkinson 's disease is a degenerative neurological condition. Symptoms worsen over time and there is no known cause. It is not considered to be a fatal disease. Nearly one million people suffer from Parkinson’s. Approximately four percent are diagnosed before the age of Fifty. Every person that suffers from Parkinson’s may experience various symptoms.
Parkinson disease (PD), also referred to as Parkinson’s disease and paralysis agitans, is a progressive neurodegenerative disease that is the third most common neurologic disorder of older adults. It is a debilitating disease affecting motor ability and is characterized by four cardinal symptoms: tremor rigidity, bradykinesia or kinesis (slow movement/no movement), and postural instability. Most people have primary, or idiopathic, disease. A few patients have secondary parkinsonian symptoms from conditions such as brain tumors and certain anti-psychotic drugs.
Schizophrenia is a long lasting/life long mental disorder that affects how a person thinks, feels, behaves, process information, and store information. People with schizophrenia think very unorthodoxly, and are not “there” completely. Schizophrenia is a very rare hereditary disorder. The symptoms can disable someone physically and mentally. Schizophrenia can be inherited from family members, or be susceptible to it later on. Suffers of the disease have an excess number of neurotransmitters and overproduction of dopamine. The excess neurotransmitters muddles the brain and causes sudden uncontrolled body movement, and inhibits thought processes. Dopamine also acts as a neurotransmitter in the brain, but when overproduced, it can interfere with other processes. The irregular circuitry also leads the brain being unable to properly communicate and control the body. Symptoms of schizophrenia usually start between ages 16 and 30. In rare cases, children have schizophrenia too.
Parkinson Disease (PD) is a neurodegenerative disease symptomized by tremor, muscular rigidity, and slow imprecise movements. Typically, the disease affects middle-aged and elderly individuals. PD is associated with degeneration of the basal ganglia of the brain causing a deficiency of the neurotransmission of dopamine.
Parkinson's disease is a progressive degenerative disorder of the central nervous system that affects the motor system. It is marked by tremor at rest, muscular rigidity, postural instability, and slow, imprecise movement. The most obvious symptoms are movement related, which include; shaking, rigidity, slowness of movement, difficult with walking, balance, and gait. Other motor symptoms include: posture disturbances, such as a decrease in arm swing, a forward flexed posture, and the use of small steps when walking. Speech and swallowing disturbances are also common motor problems that can appear as well to a patient with Parkinson's disease. Young adults rarely experience Parkinson's disease because it is more common to affect
Parkinson’s disease has four main symptoms it is associated with: slowness of movement, tremors, stiffness, and trouble with balance. In order to be diagnosed, a patient must have “two of the four main symptoms present over a period of time” (“Understanding”). Along with
Parkinson Disease is a brain disorder that affects movement, loss of muscle control and balance. The first symptoms usually include a tremor of the hand, foot, or leg which is often termed as a “shaky palsy.” The disease usually slowly progresses with symptoms getting more intense over many years. Some patients who develop Parkinson’s in their younger years have faster, more rapid, symptom signs. Much quicker than those who develop the disease at an older age. Most patients develop the disease after the age of 60 and as of 2017, there is still no cure for Parkinson’s Disease.
Parkinson's disease is neurodegenerative brain disorder that affects the brain and nervous system. When someone get Parkinson's it slowly develops in most people who get the disease. PD or Parkinson’s Disease affects people when they start to reach 60 years old. When a person is diagnosed with Parkinson's disease the brain slowly stops producing a neurotransmitter called dopamine. The less dopamine a person has the harder it is to control their abilities to regulate their emotions and body motions. Imagine not having any control of your hands, legs, arms, and emotions… heartbreaking. There is currently no cure for Parkinson's disease right now but with your help and donations made out to the michael J. Fox
The question may arise, what exactly is Parkinson’s disease? Parkinson’s disease is a progressive degenerative neurological disorder, which means that it gets worse over time. PD is more common with increasing age affecting 1% of the population above 55, with 4-10% of cases having early onset before the age of 40 (XXXX). The average age of onset ranges between 58-62 years old and is more common in men than women. The disease itself is defined by the presence of lewy bodies in neurons and a loss of dopamine. Degenerative changes to the basal ganglia affect the nerve cells in the substantia niagra that produce dopamine. This results in a decrease in the production of dopamine that is getting to the brain. Dopamine is a neurotransmitter involved with regulating movement making early signs of PD primarily motor impairments and progression of this disease can range from
From a clinical diagnosis standpoint, Parkinson’s is solely dependent on the physical symptoms that have been caused by the deficiency of dopamine because of the lack of neuron cells in the substantia nigra. Without high end laboratory maneuvers and MRIs of the brain, Parkinson’s can already be diagnosed just by observing the physicality of the patient. MRIs are usually used to rule out any other disorder that could also present the same symptoms as Parkinson’s. The primary symptoms in regards to this disease include akinesia, or loss or impairment of voluntary movements, bradykinesia, or slow movement, trembling in hands, arms head, and legs, stiffness in the trunk portion of the body and muscle flexors of the limbs, and unstable posture affecting balance. Parkinson’s is chronic and slow progressive and over time patients will begin to experience difficulty in normal tasks such as walking, talking, and other day to day activities (NINDS, 2013).
Parkinson’s Disease is known as one of the most common progressive and chronic neurodegenerative disorders. It belongs to a group of conditions known as movement disorders. Parkinson disease is a component of hypokinetic disorder because it causes a decreased in bodily movement. It affects people who are usually over the age of 50. It can impair an individual motor as well as non-motor function. Some of the primary symptoms of Parkinson’s disease are characterized by tremors or trembling in hands, legs and arms. In early symptoms the tremor can be unilateral, appearing in one side of body but progression in the disease can cause it to spread to both sides; rigidity or a resistant to movement affects most people with Parkinson’s disease,
Parkinson’s Disease is a very common disorder these days. Over 10 million people live daily with Parkinson worldwide. Parkinson’s Disease was named after an English surgeon James Parkinson who wrote a detailed description essay called Shaking Palsy in 1817. The average age for Parkinson’s Disease is between 45 to 70 years old but you can also have juvenile or young onset as well. Most common symptoms of Parkinson are tremors, bradykinesia or akinesia, or rigidity or stiffness, and balance disorder. Parkinson’s Disease doesn’t have a cure and the cause is unknown it could be a number of things genetics, environmental triggers, age, or gender. Parkinson’s Disease happens because the dopaminergic neuron dies and
The main symptoms of this type of parkinsonism are tremor, rigidity in the arms and legs, and bradykinesia.
Parkinson's disease is a progressive neurodegenerative disease, it recognised as a progressive disease because it progresses and worsens over time and during the disease there is a loss of neurons therefore it is identified as neurodegenerative. In Parkinson's disease there is a loss of particular neurons called dopamine neurons, dopamine neurons are able to produce a signalling chemical, dopamine. This chemical is important for allowing the body to make normal movements, primarily dopamine neurons are found in the substantia nigra area of the brain, it is located in the mid brain above the spinal cord; when these neurons are lost there is a reduction in the amount of dopamine in the brain.
