1. Fatigue and dyspnea on exertion are two common symptoms associated with mitral valve dysfunction. Many patients may not even show any signs and symptoms in the initial years except tiredness and fatigue. According to Shipton & Wahba, signs and symptoms of mitral dysfunctions include dyspnea on exertion, palpitations, orthopnea, chest discomfort, paroxysmal nocturnal dyspnea, and eventually leading to signs of right-sided heart failure. Although, mitral dysfunctional may be…

Introduction Alzheimer’s disease (AD) is a complex, irreversible brain disorder that causes nerve cells to die within the brain, progressively affecting dysfunction in memory and cognitive ability, behaviour and language problems (National Institute on Aging, n.d.). Primarily this disease affects older adults over the age of sixty, although it is not considered a normal part of the aging process (Dementia Alliance International, n.d.). AD is considered the most common of the dementia diseases, a…

Alzheimer 's Disease Alzheimer’s disease is not a new disease. “Alzheimer’s” was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906. Alzheimer’s disease is an irreversible, progressive disorder involving neural degeneration in the cortex that slowly destroys the memory and thinking skills, and eventually the ability to carry out activities of daily living (Karch, 2013). In most people with Alzheimer’s, symptoms first appear in their mid-60, and accounts for…

From a long time, effective aids of interrogation are sought after. Studies have shown that uncooperative accused or subjects do no give up information about cases vey easily. The most common and impatient way is torture, which in todays times is not at all preferred. In various cases police investigations direct methods of interrogation have produced better results than physical coercion which has proved to be painstaking and time consuming. When manipulative and hardened offenders are…

C.M an 85 year old male came to the hospital presenting with short of breath, cough, increased respiratory effort, and wheezing. He was diagnosed with Pneumonia. C.M is a former smoker. He smoked a half a pack of cigarettes for 25 years. When smoking, the toxins breathed in irritate the respiratory system causing inflammation. Smoking for 25 years probably contributed to chronic bronchitis. C.M had a cough. The cough could have been from the chronic bronchitis. The bronchial mucus gland…

develop dementia which shows the commonness of the condition in UK. Dementia can be divided into varies categories and the most typical condition which will be discussed is Alzheimer disease. Alzheimer’s disease (AD) is practically a condition where cholinergic neuron of nucleus basalis of Meynert has declined its function and affect an essential neurotransmitter; acetylcholine which is rich in…

In order to understand the hypothesis, first we must understand what is amyloid-beta, and how it is synthesized. Amyloid-beta is a peptide cleaved from the amyloid-beta precursor protein, which is a larger integral membrane protein found concentrated in neuronal synapsis (Masters et al., 1985;Glenner & Wong, 1984). An existing mutation in APP would lead to an increased cleavage and to a different availability of its sub products, hence increasing the amount of amyloid-beta being synthesized. A…

During my rural community clinical placement at Hunter ACAT in Newcastle, I visited a patient Mr. X with a community dementia nurse who was referred to her by a geriatrician. This referral was made so that the patient and his carer can receive some education related to dementia and ways to cope with this disease. The patient was recently diagnosed with dementia and was being cared for by his wife Mrs. X. This lovely couple was finding difficulty in coping with the newly changed condition in the…

However, according to Swift (2009) evidence on the etiology of BPD is conflicting based on some research supporting there is a biological basis for the disorder. This research identifies brain injuries and adrenergic, cholinergic, and serotinergic impairments as contributory factors to the dysfunctional patterns in BPD (Swift 2009). On the contrast, most clinicians and researchers agree that disturbed relationships are a core component of Borderline personality disorder…

1. The pinna or auricle directs sound waves into the auditory canal. The eardrum vibrates according to frequency. Vibration transmitted to malleus then incus and then stapes of the middle ear. When the stapes vibrate, the membrane of the oval window is pushed in and out. This created the fluid pressure in the perilymph. Pressure waves enter the Scala vestibule then Scala tympani and then round window. This is where the walls become deformed in Scala vestibule and Scala tympani. Pressure…
