Glucocorticoid medications were first reported to cause cognitive deficit in patients with steroid psychosis in a review of 13 patients in 1979 by Hall et al.; intermittent memory impairment was seen in 71% of patients and persistent memory impairment in 7%. The term “
Dementia-like symptoms have been found in some individuals who have been exposed to glucocorticoid medication, often dispensed in the form of asthma, arthritis, and anti-inflammatory steroid medications. The condition reverses, but not always completely, within months after steroid treatment is stopped.
Research has shown that individuals using Prednisone in high doses or for prolonged periods were more susceptible to the development of dementia as compared to other steroidal medications. However, any corticosteroid used in high-doses has the potential to exacerbate dementia.
Sacks and Shulman [1] reported a 72-year-old patient who developed severe dementia after taking an increased dosage of prednisolone for at least 3 months but resolved after discontinuing medication.
However, they often have an adverse effect on mood, sleep and memory and many patients prescribed steroids report cognitive decline and memory impairment.
It has also been well established that corticosteroid medications can occasionally cause mental disturbances and impairments in memory performance that are reversible.
Clinical Manifestation Early indicators of steroid-induced psychosis include confusion, perplexity, and agitation that typically occur within the first five days after initiation of treatment (6-7). Patients may go on to develop hallucinations, delusions, and cognitive impairment (2).
People with dementia often rely on their routines as a source of comfort. A daily routine helps a person know what to expect. This means that a sudden disruption in routine may cause dementia symptoms to get worse. This is especially true if a person experiences stress.
Symptoms of vascular dementia can begin gradually or can occur suddenly, and then progress over time, with possible short periods of improvement. Vascular dementia can occur alone or be a part of a different diagnosis such as Alzheimer's disease or other forms of dementia.
Prednisone affects areas of the brain that manage the regulation of different neurotransmitters, including serotonin and dopamine — the “feel-good” hormones. Feeling happy is a great side effect some people feel with prednisone. Other responses are more menacing, especially if you don't know what to expect.
Alzheimer's disease is the most common type of dementia. Alzheimer's disease is thought to be caused by the abnormal build-up of 2 proteins called amyloid and tau. Deposits of amyloid, called plaques, build up around brain cells. Deposits of tau form "tangles" within brain cells.
Psychiatric side effects including mania, depression, psychosis, and delirium, are extremely common in patients treated with corticosteroids.
How long to take it for. This depends on your health problem or condition. You may only need a short course of prednisolone for up to 1 week. You may need to take it for longer, even for many years or the rest of your life.
There is no set limit on how long you can safely take prednisone. It depends on the dose of prednisone and the condition being treated. It may be prescribed short term or long term. The dosage will be adjusted or stopped based on your response or lack of response to the medication.
Age. Age is the biggest risk factor for Alzheimer's, as it is for most types of dementia. This means that a person is more likely to get Alzheimer's as they get older. Above the age of 65, a person's risk of developing Alzheimer's doubles about every five years.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
Drug-induced dementia is usually reversible with the discontinuation of the offending drug. In situations where structural changes are present in the brain, cognitive deficits may persist. The complications would be no different from those that occur in patients with dementias due to other causes.
However, steroids are also known to increase irritability, anxiety and aggression and cause mood swings, manic symptoms and paranoia, particularly when taken in high doses. High doses, especially when taken orally, cause nausea, vomiting and gastric irritation.
Corticosteroid-induced psychiatric disturbances are com- mon and include mania, depression, psychotic or mixed affective states, cognitive deficits, and minor psychiatric disturbances (irritability, insomnia, anxiety, labile mood). In children, these effects commonly manifest as behavioral changes.
People who use steroids often report they experience: mood changes • increased aggression – roid rage • violent behaviour • frustration • depression • over competitiveness • anger • irrational behaviour • addiction or dependence. Regular, heavy steroid use can lead to tolerance and dependence.
