People engaging in punding find immersion in such activities comforting, even when it serves no purpose, and generally find it very frustrating to be diverted from them. They are not generally aware that there is a compulsive element, but will continue even when they have good reason to stop.

Revision as of 21:10, 14 October 2021

Punding, a possible symptom of dopamine dysregulation syndrome (DDS), is the repetition of complex motor behaviours such as collecting or arranging objects.

Punding is a term that was coined originally to describe complex prolonged, purposeless, and stereotyped behaviour in phenmetrazine and chronic amphetamine users, by Swedish forensic psychiatrist G. Rylander, in 1968.[1] It was later described in Parkinson's disease,[2][3] although the vast majority of all cases have occurred in patients with Parkinson's disease being treated with dopaminergic drugs.[4] It has also been described in methamphetamine and cocaine users, as well as in some patients with gambling addictions, and hypersexuality.[5]

Punding activity is characterized by compulsive fascination with and performance of repetitive, mechanical tasks, such as assembling and disassembling, collecting, or sorting household objects. For example, punding may consist of activities such as:

  • collecting pebbles and lining them up as perfectly as possible,
  • disassembling wristwatches and putting them back together again,
  • building hundreds of small wooden boxes
  • trying but failing to systematically remove the entire contents of all the drawers and shelves in the home and sort through all their contents.

People engaging in punding find immersion in such activities comforting, even when it serves no purpose, and generally find it very frustrating to be diverted from them. They are not generally aware that there is a compulsive element, but will continue even when they have good reason to stop. Rylander describes a burglar who started punding and could not stop, even though he was suffering from an increasing apprehension of being caught.[6] Interrupting can lead to various responses, including anger or rage, sometimes to the point of violence.[7]

Punding has been linked primarily to an overstimulation of the Dopamine D1 receptors and, to a lesser extent, of Dopamine D2 receptors which has been proposed to lead to substantial changes in the striatum, especially its dorsal and ventral areas and the nucleus accumbens which are some of the main dopaminergic areas of the brain and regulate psychomotor functions and reward mechanisms; on the other hand, it has been noted that patients with Parkinson's disease treated with dopaminergic drugs that selectively activate only Dopamine D3 receptors are the least likely to develop punding.[4]

Regarding treatment, this is mostly the same as for dopamine dysregulation syndrome but will vary depending on the cause: for patients with Parkinson's disease, their doses of dopaminergic drugs like levodopa must be reduced;[8][9] while people addicted to dopaminergic stimulants like cocaine or amphetamines should be counseled on their issues of addiction and referred to an appropriate drug rehabilition program.[10]

Medications that have proven effective in the treatment of punding are atypical antipsychotics like quetiapine or clozapine.[11][10] Amantadine has also reported to be fairly effective, while memantine, an analog of amantadine with a more targeted pharmacological profile has not been evaluated but would presumably have similar efficacy to amantadine.[10][4][12] Selective serotonin reuptake inhibitors have been found to be of virtually no use, although in a handful of cases they have led to the resolution of symptoms, especially sertraline but only in high doses (the fact that sertraline also activates Dopamine D2 receptors is presumably involved.[9]

While treating the root cause is considered to be the mainstay of treatment, in cases where a reduction in the consumption of dopaminergic substances of any kind (medications or drugs) is unacceptable (such as when reducing the dose of levodopa in a patient with Parkinson's disease would lead to an unacceptable worsening of the symptoms), are the type of situations when medications are most frequently considered, usually as add-on therapies.[9]
