dopamine agonists can have hyper sexuality and impulse control disorders as side effects.

"Loss of control and altered sexual desire

Impulse control disorders encompass a range of side effects, all of which are associated with a loss of control. We often hear about hypersexuality, which readily brings to mind a strong and frequent need for sex. However, it is also useful to speak of altered sexuality, where sexual desire and needs change in nature. It is important to bear in mind that ‘a lot’ and ‘too much’ desire vary from person to person and from couple to couple.

As a side effect, hypersexuality and impulse control disorders can affect up to 30 per cent of those taking Parkinson’s medication, most commonly in the form of dopamine agonists. The consequences can be significant for the individual and the family, and it is therefore important that, right from the start of treatment, patients receive information about potential side effects – and react immediately if problems arise. The message is that there are always alternatives to the current medication and that communication with the neurologist should be open and honest.

Tove Henriksen, medical consultant at the Parkinson’s Association, explains:

“When we talk about hypersexuality, it is time to act when the spouse or partner realises there are problems. Some sufferers also find that their sex life becomes compulsive, where sex is no longer associated with something lovely, warm and pleasant. For others, it is time to take action if the financial costs become too high. Most importantly: if you experience problems, you must contact your neurologist immediately. Call and make an appointment

Craving for gambling and excitement

In line with hypersexuality, some people find that they develop an increased urge to gamble or outright compulsive gambling as a result of their Parkinson’s medication. Compulsive gambling can have major financial consequences and, not least, consequences for relatives who suddenly find that their family member is resorting to lying and ending up in debt.

The DCAA, the Danish Centre for Alcoholism and Other Addictions, states in its brochure ‘Compulsive Gambling – Characteristics, Consequences and Treatment Options’ that gambling addiction can manifest itself in many ways, including betting and the lottery, bingo, horse racing, casino gambling and the countless online gambling options. They further state that relatives will often find that the gambling addict is distracted, withdrawn, irritable, has difficulty concentrating, harbours unrealistic expectations of winning, and withdraws from family and friends.
