Benzodiazepine withdrawal syndrome (BZD withdrawal) is the cluster of signs and symptoms that may emerge when a person who has been taking benzodiazepines as prescribed develops a physical dependence on them and then reduces the dose or stops taking them without a safe taper schedule.
A study in 2000 found that long-term benzodiazepine therapy does not result in brain abnormalities. [76] Withdrawal from high-dose use of nitrazepam anecdotally was alleged in 2001 to have caused severe shock of the whole brain with diffuse slow activity on EEG in one patient after 25 years of use. After withdrawal, abnormalities in hypofrontal ...
The committee found that the regular use of benzodiazepines causes the development of dependence characterized by tolerance to the therapeutic effects of benzodiazepines and the development of the benzodiazepine withdrawal syndrome including symptoms such as anxiety, apprehension, tremors, insomnia, nausea, and vomiting upon cessation of ...
Post-acute withdrawal syndrome (PAWS) is a hypothesized set of persistent impairments that occur after withdrawal from alcohol, [1] [2] opiates, benzodiazepines, antidepressants, and other substances. [3] [4] [5] Infants born to mothers who used substances of dependence during pregnancy may also experience a PAWS.
With long term exposure of alcohol from the pregnant individual to newborn infant, there are withdrawal symptoms from the central nervous system depressant. These traits were characterized by tremors, hypertonia , restlessness, excessive mouthing movements, inconsolable crying and reflex abnormalities.
Chlordiazepoxide can cause physical dependence and what is known as the benzodiazepine withdrawal syndrome. Withdrawal from chlordiazepoxide or other benzodiazepines often leads to withdrawal symptoms that are similar to those seen with alcohol and barbiturates. The higher the dose and the longer the drug is taken, the greater the risk of ...
Repeated benzodiazepine withdrawal episodes may result in similar neuronal kindling as that seen after repeated withdrawal episodes from alcohol, with resultant increased neuro-excitability. The glutamate system is believed to play an important role in this kindling phenomenon with AMPA receptors which are a subtype of glutamate receptors being ...
Withdrawal symptoms are the new symptoms that occur when the benzodiazepine is stopped. They are the main sign of physical dependence. [130] The most frequent symptoms of withdrawal from benzodiazepines are insomnia, gastric problems, tremors, agitation, fearfulness, and muscle spasms. [130]
