  • Causes Of Parkinson's Disease

    Parkinson 's Disease is caused by the death of dopamine-generating cells in a region in the midbrain called the substantia nigra. When dopamine levels decrease, it causes abnormal brain activity, leading to signs of Parkinson 's disease. The dopamine released by nerve cells of the substantia nigra stimulates another brain region, the corpus striatum. Without enough dopamine, the corpus striatum cannot control its targets, and so on down the line. Ultimately…

    likely to affect the middle-aged and elderly people than the young people. Most people live with this for years until noticing it. This type of disease happens in the brain, the nervous system, and the areas are called the “basal ganglia” and the “substantia nigra”. A person’s brain gradually stops producing dopamine, if you don’t know what dopamine is, it is a neurotransmitter for the body. When someone has less dopamine inside of them it reduces their ability to coordinate their body movement,…

  • How To Identify Parkinson's Disease

    In 1817 James Parkinson introduced Parkinson’s disease after having six patients experiencing involuntary unsteady motions that didn’t related to other disease out at the time. (Lees et al 2009). Parkinson’s disease affects the central nervous system and it leads to severe troubles with body motions. Symptoms include shaking, stiffness, slowed body movements, unstable posture and trouble walking (Singh and Pillay 2007). Now 200 years later this disease is the most common movement disorder in the…

  • What Is Parkinson's Disease Psychosis

    Disease Psychosis Parkinson’s Disease (PD) is a neurodegenerative movement disorder, affecting over six million people worldwide. The pathological finding associated with PD is the degeneration of dopaminergic neurons of the pars compacta of the substantia nigra leading to the depletion of dopamine in the striatum. Parkinson’s disease psychosis (PDP) is a common symptom of PD but is difficult to distinguish. Although it can occur at any stage of the illness, it is a particularly salient issue…

    there are treatments to reduce the symptoms by medications and surgery. WHAT IS PARKINSON’S DISEASE? It is a brain disorder affecting brain cells in the brain. Parkinson’s affects neurons in an area of the brain called the substantia nigra that produce dopamine (dopamine neurons). As dopamine level falls, people develop uncontrollable shaking (tremor) in their hands and body. SYMPTOMS: The symptoms vary from person to person…

  • The Effects Of Parkinson's Disease

    “Parkinson's disease is movement and neurodegenerative disorder with progressive dopaminergic neuron loss in the substantia nigra along with Lewy body formations in the central, enteric and peripheral nervous systems”. Parkinson's disease (PD) was first described in the essay entitled, ‘An Essay of the Shaking Palsy’ by James Parkinson in 1817. Parkinson occurs when the substantia nigra, the nerve cells (neurons) in a part of the brain,…

    membrane fractions of PD midbrain (Timmons et al., 2009). PKB and its phosphorylation at Ser473 is also consistently reduced in the dopaminergic neurons of the substantia nigra with loss of these neurons and hence are consequently reduced in PD. Another study has confirmed reduced phosphorylation of PKB at both Thr308 and Ser473 in substantia nigra dopaminergic neurons in PD patients (Malagelada et al., 2008). It suggests that reduced phosphorylation of PKB is restricted to dopaminergic neurons…

    that sends messages from the brain and different nerve cells in the body. Dopamine is considered a chemical that is produced in three different areas of the brain. The areas of the brain that are affected by Dopamine are the hypothalamus, substantia nigra pars compacta and ventral tegmental area. Dopamine is linked to movement, memory, attention, inhibition of prolactin production, learning, sleep, mood, pleasurable reward, behavior, pain processing and cognition in the body. Symptoms of…
